>In scorpion flies, when the males’ rape-arms were disabled by researchers, females fought males off. The “disabled” male scorpion flies soon brought females “food gifts.” These “gifts” threw females off-guard, enabling males to rape females even more easily.

Exactly - males do not possess morality and everything they do is a transaction in pursuit of one sided benefits. You can't make them genuinely good, you can only eliminate their option to be bad and force them to consider displaying good behavior as a viable pathway to obtaining said benefits (you'll still have to counter their adaptations on the go, because they'll never stop trying to dupe you). This is why they abruptly change their behavior when you're "bagged" (see: countless stories from women whose husbands were perfect unicorns until a child was born). They no longer have a reason to feign niceness because you'll stay either way.

Optimal strategies would be countering male resource monopolization (having as much money as possible) and (for straight women who absolutely need male company) feigning commitment by leading men to believe that you will soon become a secure option, siphoning resources from them in the meantime. Remember, they benefit from your guilt and your maladaptive desire to be the bigger person. Moids want you to empathize with their violent manipulative attempts to secure reproductive success while guilting you for looking out for yourself. They live by the notion of "do as I say, not as I do".
