• This 'UFO' is just a jet exhaust.

• This 'UFO' is just a missile.

• This 'UFO' is just an airplane or a helicopter viewed through night vision goggles..

All of this information is readily available. But the mainstream news media ignores it and keeps pushing the "UFO" narrative because it gets them more clicks. That should tell you everything you need to know about the mainstream news media.

The over-the-top amount of emphasis he's put on the whole "I'm not going to kill myself" trope, up to and including getting "$whacked" tattooed on his arm, strongly suggests that he set this up as a way to cast himself as a victim of some grand conspiracy, give his death meaning, and build himself up into something he wasn't.

This would be consistent with with his grandiose personality and inflated ego.

You could tell from the gunplay, the rock-star lifestyle, the dabbling in crime, running for president, engaging with political intrigue etc etc etc that he wasn't satisfied with just being a successful software designer. He desperately wanted to be something more (gunfighter/rock-star/president/mobster/secret-agent etc). And by invoking political conspiracies upon his own suicide, he gets to be remembered as a secret agent of sorts - someone who the US government had to off because he "knew too much". That's way more exciting and meaningful than being a dreary software engineer enjoying a quiet retirement until he dies of old age.

Now I don't think this is why he killed himself. I think he killed himself because he couldn't face spending the rest of his life in prison, and that became a reality for him when Spain announced they'd be extraditing him. But I think the whole Qanon/secret-agent schtick he pulled at the end was just his final larp, so he could die as something more than just a software designer. Which is basically the dragon he's been chasing his whole adult life.
