According to isoko tradition
If a legally married woman went outside to have an affair with another man,
Her husband and kids will start dying one after the other.
But in this case it was only the husband and the family took it upon themselves to disgrace her and the boyfriend

…see the yeye tradition? Instead of killing the adulterers, it now resorted to killing who didnt commit the sin.

What kind of useless tradition is that, no be who commit suppose die?

So the only thing a woman who hates her husband needs to do to kill him is just to start sleeping around.

Backward tradition

This is not how it works oooo..... The thing is if the man is aware of her sleeping around due to his inability to support his wife and family that is when the above mention happens...if the man is not aware the woman the bears the wrath on herself by have strange sicknesses.
