The lemma of my moral framework

I have thought a lot recently about my morals, and what I can use to justify at the point where ethical arguments come down to “well, why do you think that” and the answer can be nothing but “I just feel it to be right”. In my case, I believe that the base assumption in my moral framework is the importance of bringing joy to people. Things which allow more people to experience more positive interactions with each other, like games, writing, art, and talking are the things that I work to allow most, that I believe the most work as a society should be put in to facilitating. If someone is suffering, that means they are likely being at least partially prevented from doing one of these things, and we should work to ensure they have access to these things no matter what, no matter how evil we think they are, it is vital to keep their ability to have these positive interactions alive. For the ultimate thing, in the human experience, is to be overjoyed by the people who you helped make smile.
