Keep in mind the guy isn't all victim either. The guy tried to the snake dude again for money in this reincarnation but it won't go the guy's way again, no. He ruined the snake's peaceful life, what's to losing your pride as a man to being betrayed—sold to be butchered by the people? The guy took advantage of the snake's innocence then, severing their kind bond due to greed swallowing him whole..Now it's the snake's returning the favor by swallowing him in his own way since clearly he still harbors special interest despite spite but still enough to put the guy through the wrath of being taken advantage off
I'm not justifying it hell no but you can't deny he didn't instigate that and that's there's no reason to do him wrong when clearly, he too, had fault and started the foul play first. You can't say it wasn't the consequences of his actions messing with a literal a deity who HE taken advantage of first. He's just as toxic. Did the snake ever gave him consent to have his body entangled and then pulled to be ripped off? When he was living peacefully until he saved someone who'd destroy his resolve in leaving humans alone. Him especially, he gave that snake reason to go back and get back at him

the seme wasted his damn looks with that unnecessary rape bro
