Two things can be bad at once.
What the USSR became doesn’t invalidate Lenin’s critiques of capitalism and bourgeois society.
Lenin’s moral authority to proselytise vanished during his time in power. There is no need to quote him like this, and therefore portray him in a positive light, when others have said similar before, during, and after his time.
For example:

I have no issue portraying Lenin’s many contributions to marxist theory in a positive light.
It is possible to condemn one’s actions where appropriate while still acknowledging they were right about other things.
