Multiple references to suicide (making a murder look like a suicide, idioms involving hanging, etc). Nothing happens but it is discussed from a crime standpoint (no one is suicidal either).
When Madison tells Gary about how she wants her husband killed, it is very heavily implied that he abuses her, though only non-physical violence is mentioned. Nothing shown. Several characters want their spouses murdered, but nothing happens.
Madison is portrayed very sexily, it's something she initiates on her own though and is always consensual. Gary's co-workers make several objectifying comments about how he is hot and they would sleep with him. Multiple characters call women sluts.
A woman wants her husband murdered, but when pressed in court she says she didn't mean it and hugs him. They make up. It's not clear why she wanted him killed.
Madison mentions her husband forces her to be on a diet and doesn't let her eat certain things, but this is not by choice and quickly stops when she leaves him.
A cop beats up several teenagers (not shown, just mentioned as something that happened in the past). Heavily implied they were Black teenagers and he (white) did it because he is racist.
It is very heavily implied that a character is murdered by suffocation with a bag over their head. The character is absolutely murdered for sure, it's just not clear if the bag was what killed him.
