Why do some people glorify beatings and violence while others don't?

I wonder what causes different reaction in people that can be raised under similar circumstances. While one copies the same thing, even glorifies it, the other ends up hating it and doesn't repeat the cycle.

John underwent hardships growing up. He received a couple beatings and harsh tongue lashings at times. As an adult, he thanks his abusers for all the ''well deserved beatings' and harsh yellings' given to him. He claims that made him a respectful, good person with professional degrees and wants to raise his kids the same way. He really thinks disrespectful words should be met with a hard slap. He glorifies violence while claiming to be a good, citizen, obeying the lord and loves the bible.

Martin underwent the same hardships John did. He was also given that treatment and actually grew up hating it. He actually cries when remembering those times and never wants his future kids to undergo what he did. He doesn't accept what his abusers did to him as normal. He doesn't normalize it and even hates violence. He doesn't think it's normal to get assaulted for words. He even becomes a non-beliver in the end and feels good things should be done from free will, not out of fear of getting punished by god. He also grew up hating the bible.

If both were raised similar and even in the same year, and same circumstances, what causes differents reactions? One grew up glorifying the abuse he received (even giving too much credit to that) and the other never did.
