I've deleted my post as it won't do anything except get downvotes, but I do agree with what you are saying.

I'd imagine that all great man have had a private life that's colorful, to say the least.

But at some point your personal and private conduct does being to reflect on your character, as true character is consistent (as you said), whether you're in front of a group of people or are in the bathroom by yourself. Otherwise, it's more of a persona than anything else.
