Anger can be a useful emotion. It can keep you going through hardship, and keep you focused on your goal when distractions appear. By all means, allow it to be fuel. With some supervision, allow it to be your steering wheel or your accelerator. But don't let it be the driver. Anger is a terrible driver, and it will wrap you around a tree if you let it.



Maybe you're talking to the queen solely because you want to gloat. Maybe you just want to see the fear in her eyes, and to laugh as she begs for mercy. Clearly you are savoring your dominance over her. But I want to believe that you are also stalling because you aren't as sure as you claim that you want to kill her at all. I dearly hope that part of you is revolted to go so far. It is a drastic thing to deliberately take a sapient life, and it is a choice that you should doubt, even when circumstances do force you to make it. Treasure that doubt. Every time you kill is easier than the last, and the easier it is to kill, the easier it is to do so inappropriately. Probably the queen has nothing to offer that would be worth the risk of keeping her in Equestria. Probably it does not matter, in and of itself, whether she is removed from Equestria now by death, or later by banishment to another plane. Perhaps her death would not even harm anypony other than her. If we look only at immediate consequences, the utility cost of killing her would seem to be smaller than for most murders. But are you sure the next time you consider killing, when you are more used to the idea and hold fewer reservations, the consequences will again be relatively mild? Revenge won't bring 'Tia back, and it won't make you happy. Revenge is not a concept you need.
