Thats fucked up. But what you have to remember is guys are like this. They're competing for girls and they don't give a shit about ethics.

My mates are arseholes when it comes to pulling, my close mates who know nothing about game. Example - we're in a bar and i'm chating to this girl, i get her number, nothing major, and you think he'd be pleased for me like wd dude but no he starts putting me down - she wasn't that nice, you were talking to her weird blah blah. Or i'm out in a club, this girl likes me and she's dancing with me, my mate starts trying to pull her. Or were in a queue and I'm chatting to some birds and my mate barges through us all to get attentiion and act like an arsehole.

So, i had a moan about it once - wa wa wa why can't you just be happy for me and not act like a nob? But, it seems to be inherent that guys are competing for girls and putting you down, or fucking things up for you subconciusly they just get the tribal urge as they think they can pull the girl or whatever.
