Although it is a sad day when any so called world leader loses his or her life in such traumatic circumstances.
One must look at the bigger picture and while i don't in any way condone murder.
He was well known as basically a time waster with multiple resignations and alongside that also known to be against war and in particular "Nuclear war"
So with those traits and uncertainty and worry especially within Japan, they didnt really need a leader like him, a bumbling misfit "Boris Johnson" type...
I believe maybe that may be a reason behind todays barbaric happening
