Exactly. I asked him that if he saw someone (when we were in school) getting beaten in the playground by a bully, would he do nothing, jus because it "isn't his problem".
It all started because tonight we saw some guy being REALLY aggressive to his girlfriend. He was full on pushing her, screaming in her face and she was in massive tears telling everyone "he's never done this before, and for everyone not to do anything". All the bouncers outside were watching this guy. Literally, 3 of the bouncers surrounded him and delibarately starred at him to let this guy he was being watched, and if he tried anything he'd be pwned basically. Two of the female bouncers even told me that they know who the guy is because he's done it before... But this POS, pulled the girl away along campus so i followed and watched. He was super aggressive and screaming in her face constantly and i was just waiting for him to hit her... it was getting to that stage.
Anyway after all of this and i was walking home with my friend he first accused me of "fancying the girl" (bare in mind she was short, slightly fat and i'd never seen her before in my life). I was genuinely angry at this, him thinking that i'd just watched out for a girl for an hour, because i apparently fancied her! I was taken aback! Him thinking that the only reason i'd look out for another person is because i MUST have feelings for them made me furious! Then he told me he'd know people who'd beaten up their girlfriends before (he's from the suburbs of London and thinks he knows EVERYTHING about anything criminal) and he "KNOWS" (and "obviously" must be right, because he's from *near* London) they'd never abuse their girlfriend/wife in public. I told him i wasn't happy with that, and he didn't know this guy - all it'd take is for him to suddenly get angry and knock her to the ground. I told him chose to observe from a distance and not be seen, to assess the situation myself and to make sure she was ok.
Then he went on to spout the BS about it isn't my problem and she should deal with it herself and that her bf wouldn't have done anything to her if she hadn't have annoyed him.
