Does kakashi even like Naruto?

I agree. Kakashi likes Naruto well enough, but they are too different to get along really well. I don't think Kakashi really understand's Naruto's trauma the way Iruka does. Iruka is really a better replacement father than Kakashi for Naruto because he understands him and is better at supporting him and cheering him on. Kakashi knows that Naruto has Iruka, but Sasuke only has Kakashi to look after him.

Naruto has also shown himself to be alot more resilient than Sasuke is; he doesn't need as much looking after. When something gets him down, he bounces right back instead of brooding unhealthily like Sasuke tends to.

Sasuke is a more fragile emotionally, and more likely to run off and do something stupid (as has already been mentioned) and Kakashi and the rest of the village can't afford to let that happen, so he keeps a closer eye on Sasuke.

I don't think Kakashi dislikes Naruto more than anyone else in the team.

Kakashi usually don't smile. And I don't think he has smiled directly at either Sasuke or Naruto.
The reason Kakashi focus to train Sasuke is because he knows how to make sasuke more confident and strong just because he is like him. If naruto would have been trained by him, he would probobly not be as strong as he is now.
