But unalive self is suicide and unalive is just death, right? For example, You can unalive other people against their will...

I've seen 'unalived' used as a synonym for 'died' or 'killed' by YouTube minecrafters (e.g. CaptainSparkles) to avoid YouTube's demonitization/censorship. For example, using "I was unalived by a skeleton." instead of "I was killed by a skeleton."

Literal Newspeak in action and we're doing nothing about it.

'An hero' came before it but that was as a meme.

Unalive is mostly to avoid censorship same as ahh. But once they enter common usage it's not really about censorship anymore.
