"The only reason I believe humans even have souls is because I keep having to put their ghosts down," is what Lambert has to say to that, shrugging, as a way of saying 'no offense taken.' It's a little hard to wrap his head around the idea of monsters always being weaker than humans. Given what he's seen Sans pull off, it also seems kind of hard to swallow, but then again ... they'd taken him down, in the end.

Though whether or not Rin qualified as human was probably up for debate, anyway.

"Why seven souls specifically?"
