Killed a Long Time Ago

One argument that irritates me from many fans who believe SPN's Amy Pond should have been killed is how much importance they place on the fact that she killed recently. Specifically, Amy kill recently, Benny killed a long time ago, therefore Benny should be allowed to live with no punishment or restrictions, and Amy should be killed. I have no problem with the recent-ness of a monster's killed being a factor in how they were killed, but the entire judgment? That makes no sense. In the real world, there is no statue of limitations on murder, and there's a reason for that.
