Killing people like Culcio was the only thing he could do. The entitled magic users who created a world that only values magic. The closest he could get to his vision of a truly free world would be by eradicating the current world top.
Even though he knew Culcio or many of the others who have died at his hand had nothing to do with this current order or knew anything behind it. It was simply all he could do. Whilst it fueled his thirst to avenge his parents it also made him feel as if he was slowly climbing up a steep hill to his dream world.
[" That hill might be a mountain for me...I might not ever reach my dream world but..."] An image of Tuscko flashed through his head. [" He has the tools to climb up said mountain...I'll piggyback off of him until he gets to the top...Then...Perhaps I'll keep going leaving him behind?"]
