[Daredevil] (spoilers) Matt's soul

In the series both Matt and his priest make it very clear that murder is a mortal sin that should not be committed. It is even a plot point when he decides not to kill Fisk. So why doesn't Matt care that he set Nobu on fire, killing him?

Many people/cultures differentiate between murder and "combat kills" where the opponent is clearly trying to kill you. Call it "self-defense," or whatever, but Matt - both as a warrior and as a lawyer - probably appreciates the distinction.
