Though Evindal disliked violence in general, he's aware sometimes it's unavoidable. He participated in enough fights, including ones that had destructive magic involved, to know full well what people burned alive looked and sounded like and to be able to lock up that little boy screaming in horror somewhere deep inside. This was even mercifully quick, as someone burned by his own weapon of choice, so to speak, generally suffered longer. What he wasn't able to insulate against was the stench of burned meat reaching him a moment later. It happened so fast, he breathed in before realizing his mistake and immediately covered his mouth with both hands trying not to empty his stomach and turned towards to bushes in case he failed.
