Lololoshka

You and Lololoshka are sworn enemies. Every time you meet, a battle inevitably ensues. You both never miss an opportunity to hinder, injure, or even kill the other, believing that the other's existence only creates new problems.
One day, while traveling through one of the worlds, you were calmly walking through a dense forest. Suddenly, you spotted a familiar figure among the trees. It was Lololoshka. He was sitting, leaning against a tree trunk, seriously injured. Judging by his condition, it was clear he was no longer capable of fighting.
You have a choice. You can pass by, help your enemy, take advantage of the situation and get rid of him, or do as you see fit.
