Lol. What kind of dime store psychology did you pull that from? No, you don't have to have the same evolution as Superman. Nobody has to have the same arc as another person -- that's what makes us individuals. The same line of logic applies when thinking about how you thought about anything in your childhood vs. adulthood. Some things remain, others morph and evolve.
It's perfectly fine if you like meat, btw. Out of curiosity, why does this issue feel personal to you?
