I agree that, from the public information, it sounds like both of those terminations were potentially ill-advised. (There's also rumors that both of them were loosely tied to Yishan's everyone-in-SF policy, as it happens, but only rumors.) Obviously there's more going on than the public will ever know, unless Reddit corporate email ends up on Wikileaks, so I don't actually have an opinion on them because I don't have anywhere near enough information to make having an opinion worthwhile.
However, unless I misread this thread, the conversation wasn't about whether employee terminations were well-advised. I was talking about which Reddit employees received interminable ugliness from Redditors, and whether it was correlated with what the public knew about their performance in their jobs.
To my knowledge, there was no public discussion, vitriolic or otherwise, of either /u/kickme444 or /u/chooter's performance before their terminations, so I'm not sure what point you are making. (There were some comments that received flak for supporting /u/ekjp's "Removing Harassing Subreddits" post.)
edit: I should also note that I'm not taking any position on the merit of /u/ekjp's departure, as mediated by the Board. Probably it was the right thing to do for the site, and quite likely it was the right thing to do for her, as well, but again, I'm not privy to anything that would let me have a well-informed opinion. I am only taking a position on the vitriol leading up to it. I think we'd both agree that it would be a bad thing if the vitriol was causative -- either if the Board relented to the worst parts of the mob (instead of, say, to respectful argument about why she's the wrong CEO), or if she stepped down because she couldn't take it any more -- and I'm hoping and assuming that it's not the case.
