As it progresses MC is becoming nasty, arrogant and egoistic piece of s* that abuses his own family ... something to think about when you have a little power to abuse other poeple but nothing pleasent to actually read about. Dropped
Well written novel, mature content, inner thinking of MC is reasonable, visible are his errors and fight with own weakness of character - and also growth into more ruthless and confident person.
Also his system is not deu ex machina - it actually requires effort to work
