Here’s a thought for you: some people think Dean loves Cas as much/more than Sam. If that’s the case, why has he tried to kill himself twice in the past 4 eps when he thought Sam was dead? Beyond the obvious devotion there, think about what happens to Cas if both Sam and Dean die. There will be no one to save him. Dean knows that but i guess it doesn’t matter in the face of Sam’s death? Am I missing something here? How do people still argue Dean loves Cas as much as Sam?

That’s an excellent question. I have no idea.
