You know what was nice about being cursed and inhuman? Your ability to get places faster.
To do things that normal humans could not. Dassen had left and gone out the back to not deal with the authorities and how he looked. That and he was going straight for Gaberpin. If he couldn't deal with him in an honest legal way, then that left option two.
You know what, this would not be the first time that Dassen was about to do something morally frowned upon. He didn't care, he tried to be as best he could. He obviously learned the hard way, but when someone kept trying to kill you or those you knew sometimes you just had to take things into your own hand. Dassen was prepared for this kind of outcome though. So unfortunately he was going to have to take it. Gaberpin was getting too dangerous.
