I’m genuinely trying to understand… how do guys do it?

How do you wake up and consciously decide to tear someone else down?
To sit and plan how to discredit or destroy another person’s hard work simply because you feel threatened?
You see someone doing better than you, and instead of studying them and learning, you choose jealousy.
As in, you have a choice right... To either be happy for them and wish them well, rather you choose envy..
Make this make sense to me?
