I mean there are lots of theories.

My favorite is still the one about the fire caused by the windshield electrical heater. There is precedence on other Boeing 777s for this to have played out. It was a known problem.
If it really was a suicide drop into the ocean...why wait 8 hours...just...do it...
I am not an expert in the 777 electrical systems but the two minute delta between the last radio transmission - where there were no audial warnings and the pilots were calm - and the transponder ceasing to transmit seems unreasonable for a catastrophic event to take out these systems.
I'll bother to defend myself here -- we don't know what happened. It could have been hijacked, it could have been a CIA operation, it could have been many different things. That you conclude it was the captain doing a suicide run does smell of something strange, considering the plane was in the air for 8 hours before disappearing from satellite contact.
That's all I will say on this. Downvote me as much as you want.
The backhanded racism would have went: muslim + pilot = crash in building, not disappear in ocean. So clearly you're just trying to have a hot take here.

Even though someone might conclude that death is the preferable outcome for their situation, it doesn't mean that they won't experience an insane amount of anxiety and spend a long time reconsidering or even trying to talk themselves out of it just before pulling the trigger so to speak. They're humans until the end, with human reactions, you know?
Depressurizing the cabin to incapacitate the other crew is definitely a possibility and I think the leading theory for what happened. Like you say there is no proof either way - so we may never know with 100% certainty.
