Even courts take context into account for the same action (e.g. whether a murder was in cold blood or premeditated, whether someone stole because they were hungry or just greedy, etc).
And, yes, "there is a time and place for stealing someone’s wallet", as well.
As for those other things (whether it's equally legally bad to kill someone regardless of "class, political belief or religious belief") all of those have been contested in actual law across societies (including western ones), even 20 and 30 years ago (and tides can always turn one way or another again).
For another example of this kind of relativism, I would harm somebody in self-defense or the defense of another, but I would not harm somebody just because I didn't like them. The underlying principles are the same even though the right action is conditional on the situation.
Be careful about the precedent your setting and think about who may wield these powers in the future. I'm sure President Alex Jones will think it quite necessary to make exceptions to ordinary laws and rules when taking down the global pedophile cabal is at stake.
