-Eureka seveN (episodes 10 and 34): Soldiers aren't really dying but they're involved and civilians wielding guns are getting killed every which way.
-You might also be able to find something in the First Squad movie? Haven't seen it but that looks like a really war-focused movie. There's bound to be soldier deaths somewhere in it.
-There's probably a scene or two in both FMA series with the Ishbal massacre, too.
-Eureka seveN again (episode 43): There's a birthing scene behind a curtain (you can see their silhouettes) of Holland being born.
-Summer Wars has one scene near the end of it when Kazma is talking with his mother and touches her pregnant stomach
-Durarara (episode 2): Kamichika is standing on a ledge and steps forward to fall off (you can cut the scene before she's caught in Celty's phantom net)
-Shigofumi (episode 3): Someone (or a few people) suicide in that episode. I think episode 6 might also have a suicide scene too but I can't remember.
-Xam'd; Lost Memories (episode 14):
Its not a normal suicide really (in the sense of a realistic one) but I thought I'd add it in anyways, pff.
-Mardock Scramble The First Compression: The last bit of the movie when
-Trigun (episode 24):
-Wolf's Rain (episode 28):
-Code Geass R2 (last episode):
-Eureka seveN (episode 27):
-You might be able to find something in Yakitate Japan?
-Deadman Wonderland (episode 7): Ganta and Shiro as children are playing together with the Ace Man toy action figure (only two people though, so Iunno).
-FMA (I forget the episode):
-Heroman (episode 22): There's a scene of Joey's father's funeral (its a black and white flashback).
-(This probably totally won't work since its CGI but) Appleseed Ex Machina:
