Well, both things converged and combined really well to give Castiel a break. But I don't think Mark could be the only vessel for Lucifer. He could possess other people if they allowed him to. But he was the best Lucifer we could have, without a single shard of doubt. I would not mind if next season Michael is the one to stay in Castiel's body

Bela was some sort of victimized anti-hero. She was a victim, and after she wins over her oppressor, she becames the oppressor itself. She spent the entire season between good and evil, and when she aligned with the wrong side, she lost everything. In her last moments, she saw what was wrong and redeemed herself by trying to do the right thing the first time

Lucifer was still evil. I don't think the Mark corrupted him in the sense of turning him evil. Amara left implied that he was the Archangel closest to her and was a fundamental part in the plan to lock her away. I don't think it turned him evil, it just merely allowed him to release his true nature

I liked Meg. From the first time I saw her, I liked her. When she slashed the driver's throat to talk to Azazel, I liked her even more. I loved every appearance of her. When she died, I wanted Crowley to die screaming and bleeding. But, yes, of course, she never apologized. She actually acknowledged the evil things she had done. Most antagonists have reasons or excuses to do evil things. She merely noted she did evil because she wanted to, but never apologized. She just choose to do something good - In the same fashion: Because she wanted to

Metatron never explicitely apologized, and yes, he only care about God. However, when Amara imploded him, he had no reason for ask her to spare the Universe. I think that Metatron ended up just like Bela: He was a victim in the beginning, and eventually, decided to become the oppressor. And, in his final moments of life, he redeemed himself by trying to do something good for the first time: He convinced God to help humanity after that speech (Who was really well done, by the way) and helped them to rescue Lucifer, sacrificing himself in the way. He never apologized but his actions were his final redemption

Everybody agrees in this part. Lots of changes could've been made to get the series better
