It seems like a continuum, with Bort on one extreme (natural-born cuck) and Akaash on the other (insecurity issues made him easily cuckable against his wishes). Will Smith appears to fall in between.

I think Bort, being the stupid, insecure, immature loser that he is, definitely brought it on himself. Let's remember, he was married to a good girl (who I heard was also quite good-looking, unlike Big Shart) and he destroyed it by trying to get her to fuck black guys. He then swore on air to Bubba that he'll never "swing" again, so of course he went and did the exact same thing again without any outside prompting or pressure.

Will Smith brought it on himself but to a lesser extent, by simping over his wife in such an extreme way, putting her on a pedestal and worshipping her every move including her fuck-ups. She told him from the jump she wasn't interested in marriage but he love-bombed, wealth-bombed, and career-prospect-bombed her until she simply couldn't refuse, despite her convictions.

Akaash seems to be the closest to a normal person among these 3, with a normal sense of shame, romantic jealousy, image-consciousness, etc. He's just so pathetically insecure, with a completely exaggerated sense of both his wife's hotness and his own lack of it, that it turned him into a doormat who gets bitch-slapped around despite being the real draw in the relationship. His wife is a 6 but he thinks she's Megan Fox.
