Of course they are in some ways polar oposites but it sometimes happens with sibblings. For me there are two ways people act when they are not only child. They are trying ti be like ne another when usuall older is a hero 또는 they are trying to be as different as it is possible. It is a little childlish but it has affect on tehir character and contacts even when they are older. So I think no matter how different Stefan is from Damon in good 또는 a bad way there is still the bond that makes them save eachother lifes and that makes them family. Diferences are not important
i mean, it wouldn't hurt him to aleast give damon some respect once in a while, but no, he can't even do that! this bieng one of the soul reasons that i strongly dislike him! that and that he is really full of himself!
