There are certain actors who were so good at playing villains, negative roles or just a$*ho1es that I feel uncomfortable, or slightly creeped out the second I see them. Even when they are not in that role anymore.
For me
Rahul Bose thanks to Dil Dhadakne do and Bulbbul
Manav Kaul from Wazir, Thappad and Nail Polish.
Of course Ashutosh Rana from Dushman and Sangharsh.
Kay Kay Menon from Life in a Metro and Haider
Abhishek Banarjee because of Type Writer, Pataal lok and Ajji. (a huge fan but man I get a little scared when I see him in any role)
