tears in the rain, keeping things depressing but not hopeless Options

[rel]

I want the world in my games to be a horrible place. It should be depressing, it should feel unjust it should seem like the kind of place where taking to the shadows and fighting the system is a sane and reasonable response.

But there is a risk that if a setting is too dark, too hopeless and terrible then the players (myself included) become jaded and can't become invested at all.

The solution I have long wanted to try but have never successfully managed is to incorporate small infrequent scenes to remind everyone that there is still hope in the world. That the NPC's are human too that for all the flaws the world is still worth fighting for.
The example that first comes to my mind is the tears in the rain scene from the end of blade runner, bitter enemies coming to see each other as people.

I need help coming up with similar scenes to drop into my game to keep the setting from becoming too grimdark.
Anyone have any ideas?
