Why does some guys love to break a guy and a girl in love/relationship when they know they both love each other deeply? What satisfaction do they get?

You have hit upon one of the universal relationship question. The only reason that I can come up with why either a man or woman would want to break-up existing relationship is because we are fallen and enjoy Challenges. For those devoid of feelings, consciences, and morality their ability to accomplish said task is improved. You know, there are sick b-stards and b-tches all over...

Not just guys, women will do this just as much out of pure jealousy.

But for the guy, he could be jealous and have a thing for girl, he could be single and wants others to be single and lonely like him.

I think immaturity plays a role in this.
