Well said. Looking down on impressionable men with this sort of smug contempt is how we go further down the path.

If it kills the host, it’s not a very successful parasite, or it’s a parasitoid as only one other commenter has picked up. It’s not in parasites’ interest to kill their hosts, it usually happens when they infect a non-preferred host and the system responds differently, like the pork tapeworm Taenia solium which doesn’t kill pigs but can be lethal in humans.

A bit oversimplified but generally true for persistent bummed out. Not true for acute suicideation, which is real, a threat, and can be resolved with drugs or listening to the suicide call.
