Not in the base game, as far as I can tell. However, there are optional difficulty settings hidden in the menu. One of them "Hylea's challenge" will ask the player to have a kid in their party and keep them alive.
Barbarians have a subclass called "corpse-eater", they gain an ability to do just that.
Dead humanoid bodies can be looted for "kith meat". It is considered a food consumable.
One of the optional deserted islands you can visit has a shipwrecked crew that turned to cannibalism.
Dragons are usually optional fights in the game. Although the main quests/dlc quests may pit you against them all of the named dragons can be reasoned with first.
During one of your companions side quests you deliver messages to allies. One of them refuses to take the missive until their stalker is dealt with. The stalker can be convinced to leave or attacked.
You can hire sailors for your ships that have very little dialogue depending on what personality they have. One of them is drunkard. One of the sidekicks that can join your party also has a drinking problem.
