I consider this a feature rather than a bug. If you don't advocate for yourself and those you care about, who will? There's a certain level of ethics where you may be hurting someone else, but dealing with that is ... complicated ... to say the least!

What's more, the very "loophole" that enables a murderer to get away with murder is what an innocent person would use to be unjustly convicted of murder.

There are very few rules that will only permit good outcomes and never bad ones.
