The problem is that the law is deliberately written to be used in spirit instead of letter, and for good reasons at the onset.

For example, the "why gary why" scenario where you just openly cold blooded murder a man in public is a serious offense. But the context and intent make it not just justifiable but almost a good thing, which is why the Dad got basically a slap on the wrist for it. Same with most "crimes of passion."

So they took a loophole designed to lessen sentences for acts committed for understandable reasons and then reversed it to increase them for understandable reasons.
