will they really kill her husband? i think a monstergirl will kill a human when their life is in danger or her children attaked by someone to protect them. to find a man as husband its better to life with humans side by side.
when monstergirls kill humans then there must be a good reason to do it. i don´t think lamias kill her husband when he betray her but she will be very angry and show her husband with force that he will never do this again but if the man will not learn from his mistakes the lamia show no mercy and kill him. in contrast to humans i think monstergirls with a husband are very loyal and never betray him.
They kill you if you cheat on them? with all the other monster girls who rape men, infidelity is almost expected
"Is unfaithful" is VERY DIFFERENT FROM "Gets raped".
Goddamned traditional cultural values hate women who have been raped, hence the mindset is that getting raped is equal to cheating. Next thing they'll say is that premediated murder and suicide are exactly the same, one is done by someone else without your voluntary input, and the other by yourself entirely of your will.
