Arguably, another wolf-like creature (trying not to spoil too much) is found to have been petrified permanently in an emotionally wrenching scene. The act itself is not shown, but is mentioned, and he can be seen looking like a statue. He may still be alive and even slightly aware of his surroundings (again, a very touching thing happens), but he can never move again.
Cid's victory animation (after a battle is won, if he is in your party) is him taking a drag on a cigarette. Drinks are served at the bar in Costa del Sol.
Cait Sith, a robotic cat party member, sacrifices himself by allowing himself to be crushed in the collapse of the Temple of the Ancients, saying that while he will immediately be replaced by another identical Cait Sith, that one won't be HIM. Of course, this may not bother people much, as he's not kidding about immediate and "identical."
Everything under "Does a dog die" is also relevant, as Red XIII's species are rather leonine as well as vaguely canine.
There are tiny insects you can pick up and give to frogs in an optional puzzle area (Ancient Forest). Very small and non-detailed, and all they do is hop up and down in place, likely a grasshopper. However, many enemies in various areas appear insect-like, or move in ways reminiscent of bugs or worms.
An entire town is burned to the ground. Though many of the dead may have died due to a swordsman, it's possible others may have died from the fire itself.
In a haunted mansion hotel, ringing the bell to call the manager makes the manager descend quickly from the ceiling by a noose. It's more of a disneyland-esque atmosphere than actually scary. The manager (and everyone else in the mansion) is very much hamming it up.
(SPOILERS) There is a scene that shows the main character, Cloud Strife, and his best friend, Zack Fair, being experimented on. It's an optional flashback that is triggered by re-entering a location that you previously had access to, said location being a specific room in the Shinra mansion.
A segment of an arcology (a city built on layers of platforms) is dropped onto the level below it, killing millions. Several named characters die in this event.
Barett's friend falls down a crevasse.
During a scene involving Tifa and Barrett, the slur is used once when they're going up the stairs of Shinra headquarters. This can be skipped if you choose to go to the elevator.
Besides Cloud's mother, Tifa's father, and Aeris/Aerith's birth mother, a recording found in Aeris's parents' house tells about her father's death, and the death of Sephiroth's (human) mother factors into a flashback in a late-game sidequest.
The party also kills Hojo, but he was not exactly gunning for the Father of the Year award to start with.
For the characters yes, but for the player it's rather amusing. In a haunted mansion hotel, ringing the bell to call the manager makes the manager descend quickly from the ceiling by a noose.
One of the game's main enemies manages to control the main character's mind at several points, some in gameplay cinematic, some in fully-rendered. The entity is not explicitly a demon, but is hellish and supernatural, driving the protagonist to cause danger to his comrades.
Also, several other affected people are summoned by the entity to be sacrificed, becoming simple-minded drones clad in black cloaks, led like lambs to slaughter.
One particular segment of the game has the player navigate the party, which must include Red XIII, through a haunted cave where the souls that perished in a conflict linger, as described by Red XIII's adopted grandfather, particularly warriors of a rival tribe that opposed and often attacked the denizens of Cosmos Canyon -- and many monsters the player could encounter and fight are implied to be the manifestations of said spirits. At the very end of the dungeon, a boss battle is engaged among the leader of said tribe.
SPOILER: Aeris/Aerith's spirit also makes a brief appearance in the slum church Cloud fell in fighting the AirBuster boss in Disc 1, when the party has the option to return to Midgar at a later time after obtaining a key from the Bone Village.
Arguably reminiscent of one: A major character effectively suffers brain damage, and is seen majorly impaired and wheelchair-bound in a hospital setting. It can be upsetting to see a major character in that condition, and it's portrayed very grimly. He is treated with empathy, but the hospital cannot help him. (He does, however, recover through different means eventually)
A main character becomes severely disabled and spends time in a hospital, in a wheelchair. The mood can be upsetting for some, as it's very uncommon for a main character to end up having brain damage. (They do, however, recover)
[SPOILERS] Cloud has such severe PTSD that he subconsciously makes up false memories and a false persona and pretends to be someone he isn’t so he can live with himself. Whenever he is confronted with The fact he is lying to himself and everyone else around him about his identity and his past, he has a mental breakdown.
[SPOILERS] Cloud is so traumatised from past events he makes up false memories and a false persona and pretends to be someone he isn’t. Whenever he hears or experiences anything that contradicts his false self, he disassociates, then either makes up another memory to abide by the contradiction or he comes up with whatever reason he can to dismiss the contradiction as a lie or untrustworthy.
The ending of the original game is highly ambiguous without information given in the various sequels and spinoffs. While Sephiroth and JENOVA are defeated and the party all manage to escape, the last cutscene shows that they were too late for Holy to stop Meteor from hitting the earth, and then cuts to years in the future, showing Midgar in ruins and overgrown with plants. The only character actually confirmed to survive is Red XIII. The spinoffs set after the game do establish that civilization wasn't destroyed, but to someone only playing the original game, there's no way to tell whether it was or not.
It's not too violent; it gets damaged, then manages to land on the water to become a water-bound vehicle. I'd say just barely counts as a crash, more like an emergency-landing, but the sequence does include trigger words. Nobody is hurt or killed.
Also, a rocket ship is shown attempting to take off, but then aborting launch and falling back onto the platform, tilting but staying upright. It doesn't go up much or fall far, but a lot of danger and suspense leads up to it, though again nobody gets hurt or killed.
For comedic effect, an annoying and taunting enemy is suddenly hit by a truck for comedic effect. Non-graphic but openly shown. He is later shown to have survived and seems uninjured.
Arguably: In addition to bloodless combat, several characters are shown stabbed by a sword at a distance, still bloodless but fairly impactful. A character is stabbed in a fully-rendered sequence, though there is no blood. And in another fully-rendered sequence, a character has blood on their face in many rivulets.
