There's been multiple canonical Pokemon wars in which Pokemon died, but we never actually see them.
Team Flare literally tries to commit genocide, but they fail.
Giovanni is implied to commit suicide in an HGSS event, but it's only implied.
Ghetsis and Lusamine abuse their children, but never any physical violence.
Ghetsis is also implied to abuse his Pokemon, as seen with Hydreigon's max power Frustration, but a kid is never gonna notice that detail.
Beastiality is explicitly a thing in the Pokemon world and was legal at one point.
Drifloon and Hypno abduct children.
Yamasks are canonically dead people, and Phantumps are canonically dead children specifically.
And pretty much every dex entry for a mega evolution is body horror.
