I already know that sexual harassment and abuse of power are bad. If someone uncovers such behavior in a living writer, I will react appropriately, by demanding justice for the victims and doing all I can to change the writer's behavior. Finding out about Asimov's behavior doesn't change that.
As for Asimov, he is dead. There's nothing I can do to change his behavior anymore. And I'm not going to stop admiring his literary works because of his bad behavior.
