I keep hearing this argument, you become the thing you're fighting against. That's not true at all. What I'm fighting against is the innocent being hurt, evil being allowed to flow unchecked. When you destroy those who hurt, harm, and cause chaos, is that not helping society? The legal system is slow, what's worse, is that even when the police and those with the power to do something actually do it, the corrupt and rich, the wealthy and more affluent win. They get away with anything they wish, because they can buy the 'better' lawyers.
We have lived on this planet for thousands of years, and you say it helps us find other solutions--what solutions have we found? It's the same story and the same persistent nature of humanity to be dark and callous.
I do not ask to wipe out everyone who isn't like me, but instead, those who would do harm to others, and stand higher than the law, above it, and can't be touched.
