I remember last night, we had a web-spitting alabaster dove with 3 horns on its head kill an entire marksdwarf squad and all but one of my fortress guard. The survivor was the one that killed it. He managed to not get webbed, and then hacked off the FB's wing, leg, and finally its head. He saw his entire squad (all legendary warriors, too) succumb to violent deaths (they were all grabbed, stabbed in the head with the horns, and then thrown). One lived for a bit after pretty much having his rib cage ripped open, and I imagine his organs were showing. He was on friendly terms with most of his squad, and a friend of a few.
In his description it said he saw each of them die. He'd seen combat before, had a pretty good kill list, and was horrified each time. But after seeing that, it said he didn't feel anything. Saw ~12 dwarfs die before him, and it completely numbed him. Completely. I couldn't keep that save. I had to save-scum it out. I've never felt sad playing this game (I often enjoy losing in glorious ways) until now. I may be being a little too emotional or dramatic... but damn.
But on another note, I just wish it would stop stacking up so many "Saw @$# die and was horrified." I wish it would just lump it together and just say "Was horrified at seeing so much death lately" or something of that nature, instead of a full-essay on a dwarf description screen.
