Umm, Imran Khan isn't really... dead, you know? Unless you're speaking metaphorically, of course! I guess you can say his days as a politician are pretty much over.
On a more serious note, yes, I understand your resentment. But that still doesn't change the fact that what he did on 9th May was... well, wrong! Plus, he dissolved the assemblies, which deprived him of any leverage he had in the political game. Now, that was one stupid move, especially from a 'seasoned' politician, which caused quite an internal rift in the PTI ranks.
And lastly... well, it was the very same army who helped him become the P.M back in 2018 by crushing the opposition for him:

The key thing to ask here is: Why?
Why IK fell so sharply from grace?
