Your are your 'selfish' years. It's a decade to immerse yourself in every single thing possible. Be selfish with your time and all the aspects of you. Tinker with shit, travel, explore, love a lot, love a little and never touch the ground.
I've never had the antagonist as a favorite character in any movie, not even in a marvel movie. (I mean sure, I like Loki, but he wasn't my favourite character) While Vader was imposing and pretty badass, he was pretty in the original trilogy.
