B-But muh dozens of dead clones! Not counting minor or one-shot characters with little relevance or villains, the only pet characters of his he's ever killed was that blind Katarn/Kota knockoff from Aladdin's Rebels, which he only did to showoff that untrained jedi become wolves when they die to solidify some crazy belief he has that jedis are spiritually akin to wolves.

That and the villain from the first season, but he's an oc villain so he doesn't count.
Many also like to point to the mando queen from The Filoni Wars, but she doesn't count since she wasn't actually Filoni's baby, but rather Henry Gillroy's pet character who he actually wanted to kill off from the start and who Filoni poked fun at because of her name.
Despite this, he has no problem killing or approving the killing of major characters he didn't create, like Rukh (one of the most important characters in the Thrawn Trilogy), or even ones created by George like Jedi Master Piell (even ignoring his prominent role in Coruscant Nights 3 years prior) and even Maul (this one is sort of ironic since he and George wanted him back, and George even planned to feature Maul as a possible villain in his sequel treatments or as a character in a post-Legacy era game, which for me was going overboard since I honestly thought bringing Maul back in the first place as a major villain was a big mistake and an obvious ratings grab, but it just further shows that Filoni isn't following George's vision like many enjoy claiming).
Slightly related but also a bit nitpicky on my part I admit, I've always been annoyed by how Filoni killed off Padme's handmaiden Teckla, not because the character was important, but because it showed just how little research these people were willing to do when writing any episode. I mean her databank entry was right there on the SW.com website, and even with Hidalgo's incompetence at archiving, there's zero chance they could've missed that if they just bothered to take two seconds to use the search feature on the site, so any bullshit claims Filoni and Hidalgo made of thoroughly searching the holocron archives was clearly a load of bullshit. Filoni's crew was also lazy enough to not even look up the actress's right eye color, and the most annoying thing about it is that even wookieepedo treated these errors and Filoni Wars as above G-Canon despite Filoni Wars' T-Canon being ranked below it and detached from every other canon tier.

Of course it shouldn't come as too much of a surprise since Hidalgo and his merry band of fucktards had the databank completely scrubbed from SW.com shortly after Teckla's debut in TFW in 2011 for some reason, which was suspiciously at the same time George's negotiations with Disney officially began, and the character was killed off in 2014, but imagine being such fuck ups that you never even bother to backup said info or even bother to read any of it in all the years it was available despite Hidalgo writing most of said articles himself with Chee, or even bothering to look up the movies and cast themselves despite putting your new show on such a high pedestal. Maybe they wanted the databank removed so they wouldn't have to worry about TFW having to constantly be called out for inaccuracies, either that or Disney was already starting to make demands. Whatever it was, there was already something rotten in Denmark since 2008 but things really got fishy in 2011. It was also around this time in late 2011 that many articles on SW.com's revamped encyclopedia (which replaced the databank) started linking straight to wookieepedia despite their supposed independence.
