Best I can gather they were just making fun of Twilight together, and ALMOST became friends for a brief moment. Even if they reform, Sombra sure didn't, and I'm 99% sure Grogar will be joining him in the finale, he's too evil, intelligent, and powerful even without his bell.

Plus, Tirek and Cozy Glow were locked in Tartarus for a time (it has to speak something that they did that to Cozy Glow when she was a filly) and Grogar broke them out. If they do reform, it'll be because they prefer friendship to working for a villain, and will send the message not to be evil because it won't really get you anywhere. And if you don't reform, you'll end up like Sombra and Grogar.
