Aurgelmir did not stop with burning up the God of War Tyr as he believed eliminating this powerful threat should be priority. Any god of war is incredibly difficult to kill as their bodies are literally made for battle. The fact that even his flaming breath could not melt the skin of the being before him is already proof enough that killing them is difficult.
Aurgelmir did not feel pity to the screaming god of war though as he already signed up for his. Aurgelmir will deal with enemies of his beloved and will not turn away from violence if need be. They were already warned by his beloved but they dared to attack her despite all that. He wanted to jump in battle earlier but the Ice Queen Elona forbid him from interfering due to his connection with the Asgardian gods.
