Axel definitely reached a breaking point. I think everyone will be appalled at what he has done. You will learn what transpired in the next installment, coming at the end of this month. 

Thank you for your question and interest in our game! :D

His past will slowly unfold as it updates, but as far as the next update goes, it will not be told in full, just a bit more details on the matter.  Thanks for your question!
