I like what U said there about other guardians potential past lives... i have thought of that idea when making a backstory for my guardian. someone who was forced to commit atrocities and war crimes after being turned into an exo, and is reborn as a guardian remembering her violent history, a secret even from her ghost. feeling conflicted and undeserving of the power granted to her, i imagine she would feel a kinship with Crow and a desire to protect him, especially from other guardians. she would probably even have felt conflicted about killing Uldren in the first place
