From their standpoint, yes.

From an objective standpoint like that of the readers, no.

The Quincy were massacred because they refused to stop destroying Hollows, which upsets the balance between the worlds by removing souls from the cycle. On top of this, they weren't even really doing it for revenge - they were doing it to stay alive because the Hollows were poisonous to them - so they didn't exactly have the moral right of way when their selfish actions were endangering every other living soul. It's noticeable that none of the Quincy in the Wandenreich have attributed their actions to revenge for the massacre 200 years ago, likely because they don't care, just like Uryu.
