I hear what you are saying but honestly yes it should be ignored. For reasons of both fairness but more importantly I want justice to be blind. I don't want the police or prosecutors to be able to decide that person A was a dick or was a republican or a democrat or white / black so his murder is not as important. It could also lead to situations where the murder of a rich person is prosecuted more harshly than that of a poor one as the rich person donated so much to charity. The law has to be blind and based on clearly defined parameters.
