ethics.

Live a good life. If there are gods and they are just, then they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them.
Marcus Aurelius

I object to intellect without discipline. I object to power without constructive purpose.
Spock, in Star Trek: The Original Series: "The Squire of Gothos," written by Paul Schneider

For we each of us deserve everything, every luxury that was ever piled in the tombs of the dead kings, and we each of us deserve nothing, not a mouthful of bread in hunger. Have we not eaten while another starved? Will you punish us for that? Will you reward us for the virtue of starving while others ate? No man earns punishment, no man earns reward. Free your mind of the idea of deserving, the idea of earning, and you will begin to be able to think.
Ursula K. Le Guin, The Dispossessed

In King Lear (III:vii) there is a man who is such a minor character that Shakespeare has not given him even a name: he is merely “First Servant.” All the characters around him—Regan, Cornwall, and Edmund—have fine long-term plans. They think they know how the story is going to end, and they are quite wrong. The servant has no such delusions. He has no notion how the play is going to go. But he understands the present scene. He sees an abomination (the blinding of old Gloucester) taking place. He will not stand it. His sword is out and pointed at his master’s breast in a moment: then Regan stabs him dead from behind. That is his whole part: eight lines all told. But if it were real life and not a play, that is the part it would be best to have acted.
C.S. Lewis

Do not be daunted by the enormity of the world’s grief. Do justly, now. Love mercy, now. Walk humbly, now. You are not obligated to complete the work, but neither are you free to abandon it.
Rabbi Tarfon, Pirkei Avot 2:15

I’m no use of course, don’t accomplish anything, but if I ran away from it, tried not to know or understand, stopped caring (or being hurt or angry at how the world goes), then I’d be guilty not only of ineffectuality but also of cowardice. I hate what happens in these times, but ignoring it won’t change it.
