For Hordak, he's probably been genetically modified to be as relatively truthful as possible or has had dishonest thoughts beaten out of him. Because you just don't lie to Horde Prime, you just don't.
Also, for Hordak and his "species" they're conquerors who use brute force in getting what they want, there is no need for subterfuge when you can just break city walls and entire cities with orbital bombardment.
Horde Prime is Genghis Kahn, you don't have to lie to get what you want, you just get it. > guy who immediately believes the underling that already lied to his face when she tells him his waifu betrayed him
Hordak's self esteem is so low, he'll easily believe Entrapta would leave him. The only other person who "cared" for him was Horde Prime and Horde Prime immediately threw Hordak away when he was discovered to be a defect. Hordak legitimately has abandonment issues and will find a way to think he's worthless. He also yelled at Entrapta when his armor zapped him and he collapsed in front of his enemies. He already thinks he may have pushed her away.
Honestly, he's like me. Whenever I go to the movies/games with friends and I'm waiting for them to show up and they're late. I automatically think "Yep, they've abandoned me. God I'm a failure." I don't know why I have those thoughts, my friends are the best you'll ever find and they've never abandoned me, but I still get those intrusive thoughts of inadequacy.
