You can't judge Mayweather from a religious stand point because 1, you're not God, 2 you don't know him at all. You just know what he shows the media.
The only way anyone can judge Mayweather is as a boxer. As a boxer, he is the best boxer of this era and one of the greatest, pure boxers of all time.
Yes, he's arrogant and cocky, but I've long to see a more perfectly trained, technically sound fighter in recent years. Weather he would have done well against Sugar "Ray " Robinson or the likes of Carmen Basilio , who knows, but I know this in his most recent fight, the moment Guerreo got near him the ref was right on top of them breaking them up. Floyd knew enough to hold and wait. Great fighter, IMO.
Floyd ducks good / best fighter in the era and wimps out..
Some of my thoughts would be yeah he is cocky but i think everyone has there times of being cocky. And i will admit i have had mine by saying things that put myself above someone else and i understand it is wrong. I have been in a boxing ring before and in a boxing gym and i think he is a hard worker and hard work pays off. Because he is undefeated and makes a lot of money. But i think he is consumed by the fact he is a superstar boxer and rich he needs to realize the money he makes is not going to mean anything when God comes down to judge the world. Money is evil unless you know how to use it. He loves money and that's a fact because he boasts about it all the time. He says i want to be myself and show off my personality. Which yeah you shouldn't be someone your not. But the way he acts is very boastful and very much showing that he loves money which the Bible says your not suppose to love money.
