But as the script started to come in, I thought the only way this level of vitriol that he has works is if he's in love with Armand. There is this extraordinary psychological term called reaction formation, which is what Iago has for Othello. It's a defense mechanism whereby your impulses are so unacceptable to your ego that they're replaced by this opposite, exaggerated behavior. Santiago finds Louis incredibly attractive. Because Armand killed Santiago's maker — who I think he was in love with too — and also finds Louis attractive, the whole thing must be destroyed. It gave such a drive to his hatred. It was just something ruminating in myself that drove him forward in a very aggressive, mad, extreme, way. – Ben Daniels [X]
