Dean has suffered more than Sam?
And does it actually matter/is it something we can even measure?
I take issue with many of the points OP brought up. I would never criticize the person who made this post, but I do strongly disagree with the content, and I’ll try to address the reasons why below. Thanks to the fantastic @eruthiawenluin, who brought the post to my attention.
It’s near-impossible to quantify suffering. Both brothers have suffered; suffering is not a badge of honor but a fact of their lives. I’m not going to try to measure the levels of suffering each character has endured, because suffering can only be accurately measured by the person experiencing it. We can only present facts, so I’m going to address the points of OP’s argument and why I disagree.
Beware: Potential fandom- and Dean-criticism.
