Making the kind of inferences that the OP is making to support the idea that certain actions should be done these days is VERY problematic to say the very least.
Yitzchak married a 3 year old, Shimon and Levi killed all the males in a city whose ruler had violated their sister, and Lot offered his daughters to bad people banging on his door in Sidom. etc. etc. at the very least you need a good moral authority to tell you which things can be applied as recommendations for modern behavior in any kind of literal sense
