Kronos and his goons mass dm'd people in the SC Discord server with an invite to their server (Psychological Dysfunctions). I joined just because it is remotely connected to SC and see Koloss being in it, having chatter and all (under a different handle).
So if anyone wondered about him (doubtful), no he hasn't killed himself.
And remember, Koloss is a pedophile (posted CP in Edge Community).
