There is way more to him (Carlisle Cullen) than just being “Edward’s hot dad.”
Talk about BAMF, at 23 this dude was a vampire hunter. That’s how he was turned into a vampire in the first place! He led a torch- and pitchfork-bearing mob to hunt the vampires plaguing London (But these aren’t vampire-vampires, they are TWILIGHT vampires, which means their pitchforks and garlic and holy water were totally useless.) He’s attacked, but the vampire doesn’t kill him: instead he leaves him bitten and bleeding in the street. Carlisle knows if his father finds him he will burn him alive, so despite being in incredible venom-induced transformation pain, he crawls away to hide. And for three days he hides in a cellar full of rotten potatoes and doesn’t make a sound.
When it’s over he realizes he’s turned into a vampire which is wicked bad because he’s like the least vampire-y person ever. Like, the math just doesn’t add up: (Compassion + religious + vampire hunter) x vampirism = ERROR
He can’t go home because his religious zealot vampire-hating priest of a father would never ever accept him. He tries to commit suicide (because he can’t bear the thought of killing anyone), but nothing works, so he resolves to starve himself. And so despite the intensity of the newborn thirst, he manages to resist feeding for months. MONTHS! He starts to go bonkers from the thirst/pain/whatever, and finally loses it and slaughters a herd of deer.
Realizing that he doesn’t have to kill people, he does the most amazing thing of all: he decides to make the most of this shitty vampire life he never wanted and goes to study at great universities and becomes a doctor, spending 200 years learning to ignore the lure of human blood so he can HELP PEOPLE.
Edward had to wait 100 years for Bella? Carlisle had to wait 280 for Esme, but he didn’t spend those 280 years sitting around crying and feeling sorry for himself. Instead he was out in the world, helping people as a doctor, making a bunch of friends (including vampire royalty), inspiring the legend of the ‘stregoni benefici,’ and exploring the Pacific northwest before Lewis and Clark."
