That's the most commonly rendered version of Google's motto, which most people invoke ironically these days as they point out the latest evil thing Google did. But you can do a lot of evil stuff without ever seeing yourself as evil. And if you're measuring how good you are by how evil someone else is, you get to be one of those people who wants a cookie for not being as terrible as someone else.
I personally feel that if you are alive, then you deserve to be alive, by default and until proven otherwise. I believe that "kindness is goodness;" that you are a good person just for being the kind of person you are, and that if anyone says otherwise or tries to prevent you from being yourself then they are being unkind to you.
I believe that some people are damaged, disabled, marginalized, or ill. I believe they deserve to exist, and to participate fully in society. I think it is the responsibility of abled people to accommodate them. I believe in solidarity with these people, and in giving up privilege or inconveniencing myself in order to keep them from having to do without things that they need or that I take for granted. I believe this is best done not through individual acts, but as a society, so that the responsibility is spread out and so that they do not need to beg.
I believe that some people are dangerous, including (but not limited to) carnivores, narcissists, and white European Americans. I don't believe that being dangerous means that a person is evil or must be destroyed. I believe there are ways to coexist, that do not have to involve harming innocents. But I believe that the burden is on the most dangerous people to find those ways, not on their victims. And I sympathize with those who resist them.
I believe that Chaotic Neutral is the best D&D alignment, because I feel it encompasses (or can encompass) all of the above. I believe you don't have to be "good" to be kind to others and empathize with them. I believe that the concept of "good" is overrated, and is often used to cover for dangerous people's actions, or to condemn those who resist them as "evil."
If "good" exists objectively, it is willing self-sacrifice on behalf of another. I don't feel that it's needed in order to be kind to others, because I feel that most people are naturally kind (or at least not dangerous) so long as their needs are met. But I do feel that kindness -- both in the sense of being yourself, and respecting the rights of others to do the same -- is a prerequisite for the kind of self-sacrifice that is helpful.
Otherwise, you end up seeing self-sacrifice as good in and of itself. You don't trust people who don't give up enough of themselves for "the greater good." And you give your all for other people, who you then expect to do the same for others, until there's no kindness left in the universe because everyone's trying so hard to be "good."
Or at least, to appear good. Which is much easier.
