Would Japan have become socialist or communist had this not happened?

probably not
I don't think it could happen, Yamaguchi wasn't even much of an outlier in his views

I don't think so

Better not take any chances. Now with communism desu. Nothing signals great death and loss like some fags up on a podium telling you to take what isn't yours.

Kill those people. Often and in public.

It wouldn't have made much of a difference, It is remembered because it was a spectacle, not because his victim was significant (like Jo Cox, he wasn't)

Japan achieved labor peace in 1950s without class struggle.
