Looks like touching your wound wasn't a good thing.

The look you gave, how tense your posture became... There was no point in apologizing, the right thing to do would be to run away; but that would only make you more angry.

"Psst. Hey, calm down. It's okay." he said as a way to calm you down.

But who knew... Your "enemy", the way your mind had portrayed him, trying to calm you down?

You wanted to finish him off after he touched the wound: you just wanted to inflict a fatal wound on him now.
