On the contrary I like people that say to my face that they are going to stab me because that's the best way for them to increase their power.
It's so repulsive to see people say 1 million lies before each turn just to try to make a stab (texasdeluxe is one example).
There are also some respectable people who don't pretend to be your brother or trustworthy ally, neither your biggest enemy. They keep their distance while responding to you and providing and accepting supports (Geofram for example).
