It seems very much possible from these definitions that you can be a reprehensible, immoral, nice person.

I imagine this may be how some really bad people persuade some really good people to commit some really bad acts.

On the other hand, these definitions also mean that it would be possible to have some really moral people who were not nice at all.

I think of myself as a moral person. I rather dislike most humans. This makes me appear as a person who is not nice. I look at other humans and they seem to appear and act immorally. “Morality is relative” you say? I can only look at them through my morality “window”. Objective morality may exist. I am sure that many of the things I believe moral are among those things I would categorize as objectively moral. Whether my parameters are set too high or too low, who can say? I can only say from what my reaction to what I have seen, I have concluded that I am quite the misanthropist.
