In Cheney's defense, he is a robot sent back from the future to put humanity on the road to destruction. So it's not really fair to expect a lot of empathy from him.
Cheney is a war-monger, but in his defense, he came out in favor of gay marriage in 2004, before a lot of democrats who are on board with it now that it's not as controversial.
That might have something to do with his daughter Mary Cheney having come out as a lesbian way before 2004. In interviews before 2004 Cheney would often get asked about his daughter being gay and him being non-supportive of lgbt rights... and he'd just chide the interviewer for going there.
So really, it just shows what a terrible human being he is. He always played a position that was politically convenient... until it wasn't.
Given that, at this point, there's no incentive for him to be a bastard besides the pleasure derived from it, it seems like that's actually just who he is.
For example, President Ford was probably the most athletic President in the 1900's (he played LB). He is "known" more as clumsy and un-athletic from a set of comedy sketches[1].
1) the real lesson is shoe choice is important as a politician
Mary Cheney is a reactionary neocon chickenhawk just like dad. The only thing Cheney wasn't cold about was gay issues, probably because they applied to his own family.
