@Phantonn1 He hears about a job on his wife, he knows what orginisation is handling it, he does nothing, kills the assassin after it's taken multiple shots at his wife, finds out nothing new, orginisation sends new killers to his house, still does nothing, will prb just walk into another sniper next chapter and risk his wifes life again just to "hide his power".
He could have stopped the hit at the minimum, or wiped out the orginisation doing the hit to stop followup killers, set up actual guards around where you know the hit is going to happen, SOMETHING.
All he does is leave unfinished buisness.
