Would Alexander the Great count as a dictator or tyrant? If so, maybe he should be on the "nice" list.

I don't know how Herod Tetrarch made it on the naughty list. AFAIK he is blamed for killing only one person (John the Baptist) and I imagine there is some dispute about whether or not he did even that. Killing someone because he embarasses you isn't exactly nice, but comparted to what some tyrants did, it doesn't add up to much.
