Unless he is schizophrenic, its still the same mind that keeps continuously lying to most important persons in his life and keeps pretending nothing is happening. This sort of hard character flaw/weakness never goes alone, there are more if you care/can take a deeper look.

If you are OK with serious liars as leaders, thats fine for you I guess. Definitely not OK for me. Albeit for purely work performance, most of us can turn off our moral radar temporarily, mortgages ain't gonna pay for themselves with just good honest heart. But that's not a definition of leader, quite far away from that actually.
