You can't really attribute to someone something they did unintentionally while trying to do the opposite.
I mean.. we do all the time no? Hitler tried to make Germany great and made it shit. Mao tried to make China great and killed tens of millions. Stalin, Pol Pot.. the list goes on.
If we attribute accidental evil, why should we not attribute accidental good?
i think that's why they used the word "accidentally"
