I can't help but disagree, personally. There's a clear redline that states that the reincarnated soul retains no concrete memories of its former life. Maybe it would remember a vague feeling of being harmed or something similar, but the faces, names, and details of any memories it retains are erased. Anyone using this lore to try and get revenge would definitely be metagaming, no question about it, and should face the possibility of punishment for such.
