Reverse Jainism
In opposition to Jainism, Reverse Jainism holds that all beings are equally useless and should most likely be disassembled down to their base chemicals. Similar to Nihilism at heart, only where Nihilism simply assumes things worthless, Reverse Jainism goes the next step and does something about it.
A follower of Reverse Jainism will carry a flamethrower around at all times in order to ensure that no organism goes unpunished.
