That's really personal and it's impossible to figure exactly what goes on in the head of each fighter. IMO, if should be any thanks to God it should be for the fact it was a fair fight and nobody got seriously hurt. Same way for a prayer before the fight. To pray nobody gets seriously hurt. Thanks for the victory is just off for the reasons already exposed.
