A very simple question, but a very difficult answer, I find.
There's no long backstory, just, simply, in your eyes, which is better, loyalty, or honour?
Honour is doing the right thing, no matter what.
Loyalty is supporting those you love, no matter what.
In a perfect world, one can be honourable and also loyal. But many times, this is not the case. So, which is the greater good, to you?
