"I always acted as a guardian to protect others" Before He was banished from the island, it was his dream, Yes... After that? I didn't see that is the previous chapters, more someone who couldn't gaim power and just blamed everyone for it. (Can't blame him, I never was as destroyed that he was...)
Now we will see if he became the basic dumbass (Continue to blame other for what happend before and act like an ass - Chinese MC style...) or start to really improve and show them what he can be...
