I just backread this chat, and here are the fifth ideals for Kaladin I've seen that I think make the most sense. (I've credited them to the first person I saw saying that one, but there are multiple cases of someone else saying it later.)
- "I will save someone I know I can even if that means leaving someone I don't know I can save" -Harrycrapper | This plays into it mirroring Lirin's experience with Roshone and his son, which I think makes sense, with Brandon's foreshadowing and all.
- "I will allow myself to be protected" -Rushu42 / "I will protect myself" -Leuthie | These two do differ a little bit, but they're mostly the same. The first one seems to be letting others protect Kaladin so that he doesn't have to everything. He can rely on others. The second one is more about him taking care of himself and being willing to step back when he needs it.
- "I recognize/accept when I should not protect" (allowing people to put themselves in danger, respecting their decisions) -Kingsdaughter613 | This is one that I like a lot. It's letting others make their own choices about what to do and what risks to take. It seems to call back to Tien's death (if I remember correctly) and Maya's "WE CHOSE.", even if that doesn't necessarily connect to Kaladin.
- "I will not cause harm/kill to protect others" -tipbruley | I don't think this would extend to them being total pasificsts, as like a few people pointed out (or was it just one person?) the Windrunners are primarily soldiers, but there are of course exceptions. I think, instead, it would be Kaladin moving away from fighting being is primary way of protection, as we see with him being a surgeon for the first part of RoW and inventing therapy for Roshar. I'm not as sure about this one, and I think if it is it the wording would be different, but it seems a viable option.
I've liked all of the options people have presented and I think there are a lot of good arguments backing them up. This fandom is obviously pretty smart.
(P.S. Should I ping the people who presented the specific ideal idea, or leave it as it is?)
