So I have mixed feelings on Lucifer. Mark does incredible, as did Jared and Misha. And I love the character and enjoy watching him.

But I have zero sympathy for him. 

I mean, he clearly only cares about himself. 

Some people seem to think he cared about Jack and only turned on him because he rejected him and was hurt. But that's not true. He only wanted Jack for his power, and so when he realised Jack wasn't going to choose him over the Winchesters and Cas he lashed out and took his grace. He might have felt hurt by the rejection, but only because it was a rejection and his ego can't take that. It had nothing to do with actually loving Jack. If he truly loved him then he wouldn't have lashed out at rejection. He would've accepted it and let it be, whatever would make Jack happy. But instead, he lashed out, stole his grace and tried to get him and Sam to kill each other. That doesn't sound like love to me...

And everything with Sam. OMC! The hate I've seen Sam get about what happened in 13x22 with leaving him behind in Apocalypse World instead of giving him a chance. 
Have these people even been paying attention to the show? Have they seen what Lucifer put Sam through? 

I mean, first of all, he literally tried to end the world. So, like, that's reason enough. 

But he also possessed Sam and used his hands to kill Cas and Bobby and almost beat Dean to death, and then tortured him in Hell for centuries! So badly that Angels and Demons alike were saying that getting his soul back was a bad idea. So badly that he hallucinated him because of it. Then he tricked Sam back into the Cage by giving him false hope, tortured him more (with his own memories this time, because that was torture in a way, just pointing out his flaws...) and then when Sam still said no to letting him possess him again, he turned to physical violence. Then he possessed Cas, tricked the Winchesters for a long time, and then tried to kill Sam. 

And after Chuck ditched him again, he decided screw any progress I made, I'm pissed and wanna destroy the world again. 

Then he kills Rowena and Cas. And tries to use Mary as a bargaining tool to get Jack. 

And people try to say things like "He brought Sam back to life!" Who the fuck cares?!

He did that to try and manipulate Jack into trusting him, and to have control over Sam again. 

So anyone who thinks Lucifer deserved another chance and gave Sam hate for not giving it to him. WTF? 

Sam is the last person you should expect to give Lucifer a chance. He's had to be around him and work with him enough for someone with so much trauma because of him. Lucifer didn't deserve another chance, and Sam had every right to leave him behind. 

Also, his death was stupid. They literally spent all of Season 5 trying to stop the fight between Michael and Lucifer because it would destroy the world, and yet Dean uses Michael's powers to fight and kill Lucifer? (Plus, Sam deserved to be the one to kill him...)
