I've killed six player characters in as many years of DMing, but all have returned to life except the most recent. I never aim to kill characters and I still don't like doing it, but it stresses me out less than it used to which does allow for better storytelling.
Amani the half-elf sorcerer, killed by an archfiend (revivified by Khamet.)
Khamet the human paladin, killed by his own party (re-appeared on the other side of the world because he cannot be permanently killed through violence.)
Phoebe the half-drow warlock/cleric, killed by a mechanical dragon (Va'Kym's reincarnation dust brought her back in the body of a moon elf.)
B'doop the grung fighter/barbarian, revivified by Catherine (he was a zealot barb so there wasn't even a material cost.)
Faine the hexblood warlock, who was killed by a black pudding and revived by a teacher.
Hollow the dhampir warlock, killed by skeletons while trying to loot them.
(This doesn't include 'scripted' deaths- like Tally the drow monk giving her life to make a magic ring give her people a chance of escaping their evil goddess!) (she also got better.)
