One of our PCs was down and "bleeding out". It was my turn and no enemies were left alive, I chose not to help my party member due to me believing that my character doesn't care enough due to his past and due to some actions the downed PC took before combat.
This was not taken well by the rest of our group and I quickly agreed that while my chara had some reasons to not help, they wouldn't let people die because of negligence.
However, this got me thinking. Is it always considered an evil deed to not help a downed party memeber? Are there factors that would justify not resuscitating a party member when your alignment is good or neutral?
