Zaluzhny spoke out of line at one point .....I got the impression that pissed Zel off ....he should've stuck to the military and avoided politics and he may still be there . Probably other things behind the scenes , and I'm guessing Zal may have political ambitions too . These possibly expalin but don't excuse .
Zel had the power and he used it ......the impression I got is that in that instance he put himself above his country and got it wrong ......impression .....as neither of us have full knowledge .
Zel does't need to be a genius or perfect ....he isn't God ....he isn't perfect ......not a job requirement . And if he was actually bumped off the next man jumps up tpo take his place .
