Not sure I'd give Singhal a pass --depending on evidence provided, that said, I'd probably give someone who develops a cure for even one of the cancers a pass. It's probably not the PC thing to say, but if someone could have such a positive on their side of the scale, I think I could give them a pass.
Your example has some false equivalence, Hans is a convicted murderer, Singhal is an accused sexual harasser. Those are not equivalent.
In a purely procedural society such a hypothetical person does not get a pass --in a more relative society he gats a pass. Kind of how we look the other way regarding historical figures of importance and their flaws when what they achieved transcends those flaws.
