What's the worst thing you've ever done in a video game?

[KungKras]

In Age of Mythology, after I had built an impenetrable fortress in my city, and after my enemies had given up going on suicide missions against my heavily guarded boarders, I put my son of osiris in the center of my empire. Then I put all my villagers in a prison that I had built,, and then I sent them one by one to the son of Osiris and ritually sacrifised them (delete) to him.

After all of the slaves (villagers) were dead, I burned all the enemy kingdoms, and let no one survive.
