Palestinian Arabs supported all of them when they were at their most murderous.
For Hitler, I'm not only talking about the infamous Nazi corroborator the Mufti of Jerusalem. Palestinian Arabs helped Nazi parachutists in Palestine and they demanded the British free them when they were captured. And in 1945, for V-E day, the Palestinian Arab regiment joined the march of celebration - but displayed the swastika and a picture of the Mufti, much to the embarrassment of the British.
Saddam? Palestinians loved him, and he loved them back. Palestinians overwhelmingly supported Iraq's invasion of Kuwait, resulting in their being ethnically cleansed from that country.
And of course Palestinians have shown great love for Yahya Sinwar. Last December, Sinwar had an approval rating of 69%, it only went down to 65% in June.
Palestinians also supported Bin Laden and Al Qaeda. The earliest poll I can find is 2003, when a far higher percentage of Palestinians - 72% - said they had confidence in Bin Laden than any other Arab group.

Palestinians consistently support the world's most notorious monsters.
This isn't exactly what the "right side of history" looks like.
