I hate to break it to you brother, but that guy was not sent to heaven.
Also, self defence argument holds here. Someone was running his mouth, he also ran his. Someone threw a punch, he returned fire. No escalation. Self defence
it says "sent him to God" no mention of Heaven. God being the energy of the universe that makes up all things in which we return to once our bodies piss off the right FedEx delivery guy (or girl)
We don't know for sure but I certainly HOPE he wasn't sent straight to heaven without going through some serious and difficult reformation of the soul first
