Krugger said: I just remember her talk when I first met her in game she casually suggested freezing me in the wilderness since I was human and alive
Huh? I only see Letty mentioning freezing in Marisa's scenario, and she assumed that Marisa was done in by the cold. No threats there.
In Sakuya's scenario there was some casual banter followed by her spazzing out about "a freaky flying maid coming towards me."
Her interview in BAiJR has her stating that she just wanted to tease Reimu. The only canon bit I know about her "dark side" would be her PMiSS article that says "Letty Whiterock is feared for ensnaring humans and freezing them, rendering them useless in combat."
Attacking, subjugating, and devouring the bloody flesh of humans is the true nature of us youkai, isn't it?So what does that say about someone who wants to defy our rightful natural instincts and sweep all that under the rug?
