This guy's in the clear. He got punched in the head and had good reason to believe worse would happen. Stabbing him repeatedly went beyond his immediate need for self-defense, but that is acceptable in situations of great fear or confusion.
The fact that he thought to bring the knife and maybe even expected the confrontation does indicate that he could have taken means to avoid the fight, but ultimately, he has no legal obligation to take these measures, and tried to take them anyway! He didn't provoke an attack, and when the attack did happen, he defended it in a way that didn't go beyond the permissible. He didn't have to bring a knife, no. But if he's legally allowed to carry it, then there's no problem. He's allowed to carry the means to defend himself with him, particularly if he considers it necessary to defend himself. People mention that he could have used, say, a baseball bat instead, but he didn't have a bat on hand. At the moment of the attack, he just had a knife. He could have brought a bat along, in expectation of a fight, but he had no legal obligation to make sure that he has a non-lethal method of self-defense on hand, even when he's expecting that he might need to defend himself. Besides, a baseball bat can be pretty lethal too.
Mind you. This is all assuming that the guy actually went beyond his immediate need for self-defense out of fear. If it was premeditated, then everything between the first 2 or 3 stabs no longer falls under self-defense, in which case murder is a possiblitiy.
But apparently the judge believed the he wanted to avoid the confrontation and wanted to prevent anyone from getting hurt. Probably because that is pretty much what his behavior shows.
Anyway, the legislature that allows this is really based on the idea that a law-abiding citizen can defend their own rights from being infringed upon by the necessary means. That's a principle upheld in quite a lot of western countries. This situation falls smack-dab in the middle of that.
