I don't want to kill them, I just want them to get appropriately deterred when I whack them on the head with my survival tool. The animal aggression is still very wonky, but the devs have acknowledged that and are apparently working on a solution that doesn't involve killing. Sounds good to me.
Though it was a lot of fun the first time I cranked my Cyclops up to RAMMING SPEED and crashed a reaper leviathan.
