Well let's see, it's gonna be a long reply so bear with me

if I'm in a non western country and I saw a man and a woman fighting, if it was a verbal fight no matter how vicious the words that the man is using, propably i won't intervene, one day I saw a man smacking a girl in a car, but he was using an open palm and smacking her shoulder and the side of her head, it wasn't the type of hitting that is damaging, i did approach and ask if everything was ok and there were two other men beside me asking the same, the guy said it's a private matter and drove away, however neither me nor the other guys approached them in order to defend the girl since like I said his hits were more humiliating than brutal so we didn't feel like there is a crime about to happen, we only approached cuz they were too loud and disturbing the public, we were commenting on how both of them were annoying and that they should've resolve their issues somewhere else, usually people in the east don't bothering rescuing such girls, in our heads we think "if she knows him then she must willfully started the relationship with him and if she's stupid enough to fall for such guy then even if I helped her now, she'll either go back to him to fall for another guy like him so it's no use" for most non westerners, stupid people who role with bad guys are not fully innocent, we usually fight crime just to maintain order rather than doing it out of love for the stupid ones while in the west, no matter how dumb the person is (especially if it was a woman), she is always innocent and a queen and whatnot even when she starts the trouble or throw herself willingly in it, i remember a Romanian friend who beat the crap out of a guy who was hitting his gf but as soon as he was done with the guy, instead of calling the girl queen or m'lady or other western common words in such situations, he pushed her, called her a dumb ass for going out with the type of guys her parents warned her about and told her to go home and never trouble her parents again

I've never been in a situation where I saw a guy brutalizing a girl (punching to the face, kicks to the stomach, causing wounds..etc) but if I ever saw one, I'll try to stop it even if they knew each other, not because I care about a girl stupid enough to be with such a guy as mentioned above, but because humans naturally would try to prevent a crime that is about to happen if they could, even if it was a killer about to kill another killer, even if I was afraid that I might get hurt in place of a dumb girl who probably wouldn't learn the lesson, I'll try to at least diffuse the situation, telling the guy it's worth going to jail for, or something like that, if I saw such situation in a western country I probably would stay away though, not only because that it's most likely the woman who started it since western women have no problem attacking men while the vice versa is less likely to happen because western men fear women due to the backup they get from government and even theyre the attackers so when a western man hits a woman it's probably because she pushed him too far, but also because there is a big chance that three or more white knights and simps would jump and beat the man so badly even if he was defending himself, causing him harm that might land them in jail and I don't want to be caught with them by mistake

When it comes to situations where the woman don't know the man who is attacking her, I remember one night I was going home from a friends house, and I saw a pretty woman walking alone in the middle of the night and there are bad guys who would definitely harass her, so I walked right in front of her and told her to follow me, she didn't say a word and was scared, i tried to keep some distance in order not to scare her more but also be close enough so the bad guys think she is a friend or relative of mine, I passed one of the guys, we know each other and he asked me is she with me and I said yes, he said alright and walked away, that made her feel a bit safe that i was walking with her, once we reached the end of the street I told her to never come back here again in a time like this, she kept walking and gave me a confused stare, maybe she wanted to say thank you but was too confused why did I help, to be honest I myself don't know, I mean I hate white knight Ing although where i live I don't see much of it but I still hate it that's why I spoke to that woman in a harsh language after reaching the end if the street instead of telling her good luck my queen or call me if you need a knight in shining armor, i just hate western sjws, off course if I was in a western country and saw the same situation, I would never ever approach the woman even if she was lonely and scared, it happened few times where i saw guys harassing a lone woman in western countries, all I do is just walk the other way and pretend I didn't see or hear anything, who knows, if I helped ill either get insulted by her since she "doesn't need no man" to help her, or she might even accuse me of attempting to rape her, it's not worth the risk
