Allow me to update.
Three dead, one lost his memory, one locked in a trunk for a year, two sent to Azkaban.
Err. You seem to be mixing up the incident by which they ceased manning the post as Defense teacher with their condition “today”.
Lockhart: had his memory removed.
Lupin: felt forced to leave, now dead.
Moody: locked in a trunk for the whole school year, now dead.
Umbridge: raped by centaurs, now in Azkaban.
Snape: fled the school, now dead.
Carrow: captured by the conquering army and thrown in Azkaban?
