I have only used a single quote so I assume you decided to pick at that. Said quote may hint to a reason why-, but isn't proof for that Sans doesn't seem to know much about Flowey. I have listed two cases when he acts like he didn't know that there is a murderous talking flower around. First, he seems to think that Papyrus is being manipulated through an echo flower, not by an actual sentient talking one. Second, unlike Alphys, he seems oblivious to the possible consequences of Papyrus gathering everyone on the advice of a talking flower.

If you think Sans knows about Flowey, I suggest you look for evidence that he does. It would be much more preferable than loling on some minor tertiary evidence that happens to be a quote.

I have also included some cases of Sans not being too friendly. Not all I could find, because I happen to like Sans, and the point was to explain his behaviour not to present him as a bad guy.
