This is kind of what I meant by good and bad actions don't cancel out.

I think people are perfectly allowed to appreciate the art while knowing he was not nice as a person. People are multifaceted, both as actors and in judgement of others.

So where to draw the line is the question.

And the answer is: this isn't linear. Context matters and is different for spaces and people. For example, you state seeing the art first, finding out he was not nice later and how that shaped your judgement.

------ Spaces

Not having Picasso art in your house is clearly fine. It's your space, your personal choice what you put there.

Demanding his art be removed from all art galleries around the world is not fine. Art galleries are mostly public spaces whose role is specifically to view artistic results largely from an artistic point of view. They are allowed to acknowledge his personal life and usually do - but that is not how you judge art.

And so we have two perfectly fine and yet contradicting choices towards housing the art of Picasso.

------ People

A victim of similar abuse as Picasso dished out may not want to see his art in the gallery due to association - this is fine.

A person who simply doesn't care for that style of art may be indifferent or also not want to see it - also fine.

A person who thinks Picasso fundamentally moved the art world forward may definitely want to see this art - also fine.

And so differing people's attitudes towards Picasso are also easily understandable and fine.
