The prosecutor has argued that the 35-year-old suspect showed up in Kärrtorp armed with a morakniv, a traditional Swedish knife used for wood carving and odd jobs.
"It was a heated atmosphere on our side also, of course, but that's because they (the neo-Nazis) arrived," the 35-year-old said in court. "It was calm before that."
The court verdict said that video from the altercation showed the 35-year-old take aim before he stabbed the Nazi in the back, which signalled intent to injure.
"The district court thereby finds that (the suspect) was aware that the (victim) could die from the stab wounds," the verdict stated. "It must be obvious to everyone that it is indefensible to stab an unarmed person in the back with a knife."
The 35-year-old had said he habitually carried a knife because he lived under threats. He said that political antagonists had published a photograph of his son, along with the son's personal ID number, online.
