Why do some men behave badly?

I have always attributed this with insecurity, the need to feel better than others.....for lack of a better term, the bully mindset.....

I agree with the premise that some men do "grow out of it", they learn empathy/kindness, etc.....and some never do.....those that never do often are surrounded by other bullies in their orbit.....

I do expect this to get worse over the next 4 years.....
