For those of you who may have forgotten or are new to Fergus, he is fucking crazy. Here is my list of reasons why:
1) He tortures for fun
2) Before he kills his prey he toys with them, even giving them a chance of escape.
3) He attempted to start a nuclear war to wipe out humans.
4) He got turned into a vampire in a bar fight.

That pretty much sums up Old Fergus, Prepare for what I have now! >:D
