This list could easily have been based purely on acts of animal cruelty, so I picked just the 'best' ones. And Overlord's kill 100 baby seals achievement trumped Fable II's rabbit shooting.
Until someone actually comes up with a 'nail-bomb a kitten orphanage' achievement, I think the baby seal massacre wins the most sick.
I almost put in the 'Kick the Chicken' Achievement from Fable II, but the Call of Juarez entry already had chickens covered. And blowing them up with dynamite just seems way harsher than giving them a kick. EGGSPLOSION!!!
I don't have the energy to really hate anything properly. Most things I think are OK or inoffensively average.
I do love quite a lot of stuff as well, though.
Yes. You're right.

It's not fear. It's our moral responsibility to protect children from this sick filth.
