What is it I don't even
...
You didn't...
You just didn't compare Kaladin to the worse character from the worse book to ever gain a physical presence outside of Hell. I really can't even begin to comprehend how you could compare the character with most tragedy, growth and overcoming of the book with a retarded girl which biggest problem was that she can't decide if she prefers to engage in necrophilia or bestiality.
I mean, Kaladin got all his dreams crushed, one after another, to try and protect Tien. Then he saw his brother being slaughtered in front of him, after that he was betrayed in the worse way he could, again saw the people he cared about being killed, was sold into slavery and finally became the lowliest lifeform in the most brutal and oppressive job ever. And he STILL managed to protect, or at least try to protect, everyone around him. Managed to help a lot of people and to make them feel like it was worth living again and ultimately saved and became the personal bodyguard of the greatest highprince of Alethkar!
How can you even begin to compare that to Bella!?
