You're asking if a guy who runs up behind another man and sucker punches him is contemplative by nature?
No, he's not giving it much thought IMHO.
I bet it's the other direction. Lots of kids act without thinking at that age, but when they realize what they've caused, they are very remorseful.
If anything, I think Miles now has Hill's complete and unwavering loyalty. If Miles calls him 10 yrs from now at 3am and says "I'm in a bind and need you to come", Hill only asks where, not why, and is on the way immediately.
That's generally the way people react when someone stands by them in a shite storm.
