Well, he has the full right to support his brother though

He's not doing anything into his brother's marriage -- his brother's wife got an affair, fine, wants to get out, fine, but is it also fine to totally rip off the brother's rights? I don't think so! As a brother, this has man has the full right to support his brother, in any fight like this, legal or any other forms.

Men need respect, need equality, that's the demand, not a request! Anybody can go, but the respect and rights must stay! By the way, humans have many methods to make respect and rights stay -- which is the origin and source of all law.
