No! But due to how he died, a pretty fast death, with the axe hitting his brain he can often experiance periods of time where he just stares st a wall, he can forget that he's dead, or he can actually be stuck in the memory of the moment he died!
Essentailly a kill thats meant to be as fast as possible. It can be considered a mercy kill if its done with the intention of putting someone out of their misery. Ie: Its common in hospitals or war zones if the person is too badly injured or will only suffer.
