Only prejudiced people (including racists) would think an entire group of people defined by etnicity, race, religion, gender, sexual orientation or similar are all good or all bad.

(Notice how the racists claim "Palestinians are violent" and use Hamas' actions as "proof", as if all Palestinians were the same)

All large groups of people have the full range from good people to bad people in them.

Splitting people in groups on anything but their action and then making general claims about the behaviour of their members is always prejudiced, even when the claims are positive.

What really makes the Evil as in here is not the etnicity of the oppressors, it's the power structures that allow and even incentivises those with a capability for the evil amongst them to transform it into action with no reprecursions.

Members of the Jewish Religion include the whole range from great people to total assholes, but the State of Israel enables, condones and even incentivises the worst to act in their evil ways so long asnit's directed against a different etnic group.
