1. The Traveler (Diablo 1 and 2)
Here's a guy who just can't get enough demon killing. Regular adventuring just isn't enough for him, so he goes to the town where the demonic shit has been happening. He's the dark ages equivalent of the extreme sports guy. He spends days going deeper and deeper underground, killing monster after demon after monster. Then, he gets to the devil and kills him, leaving him trapped in a rock. After all of this, the Traveler thinks, "Well, can't just leave the devil laying about like this..." and proceeds to shove the soul stone INTO HIS FOREHEAD. Just wow. The soul stone ends up driving the traveler mad and turns him into Diablo, but it took a long time. A lot longer than a normal person I'm sure. Bad Ass Rating: 11
