I feel like the Slytherins aren't really Slytherin like...If you were in Slytherin, you would probably be Acacia. She is using her cunning ability to get what she wants, something that Slytherins pride themselves in and value. Act your house. (hahahaha....get it? Act your age? Act your house? Ah, I'm so funny.) Anyways, just my personal opinion.

Actually I did mention Casimir was deceptive himself and even praised those who could beguile others, provided they actually beguiled someone for a great reason, and someone who was actually a challenge. He spoke out against Acacia because she was taking pride in fooling someone who could probably be tricked by a Hufflepuff :p.

Besides, Casimir capitalizes on the fear of others to get what he wants, so he has this to back him up as a Slytherin trait.
