The protagonist creature represents the outcasts of society. The hunters and villagers - society. The witches' hut represent communities, which are toxic and unhealthy, but the outcasts find solace in, because they accept them and support them unconditionally, including their flaws, mistakes and advise them to continue their bad behavior. The purple creature represents another outcast, who's already a part of the abusive community. The village's children represent the new generation, learning from society. The chemist represents reality, while the tiny, poisonous spiders represent evilness, which are born from hate and pain, spreading through the whole world and taking over the essence of many, and at last, killing them.
So, the outcast, who's hated and attacked on by society, finds solace in an abusive community, where other outcasts are, believing that toxic environment is what is the true meaning of healthiness, and gets involved in unrighteous acts, against society. The new generation learn from the old and copy the old, wrong ways. At last, from the hate and antagonism, darkness births and spreads around the world, killing people. Reality once again proves, that killing the ill will only breed more illness, the tiny spiders, while supporting wrongfulness unconditionally would breed a monster, and the only true way is healing the ill by teaching them and leading them to righteousness. Both extremes end with death. The story ends abruptly, with a quiet sign, saying "Well? Will you continue doing what you're doing and let this happen? It's in the process already! Or will you stop it by becoming a healer and not an extremist hater or unconditional accepter?". Choose your path wisely! Violence breeds more violence!
