I've spoken about this before, and I will again. From my studies and experiences, I've theorized that there are 4 aspects of fighting evil, and there are even other ways to interpret this in your own ways, but here are some of my ways of viewing it. And I will share them with you.
The Fire Aspect- This one is obvious. Just think of the term used time and time again. "Fighting fire with fire." That's what this one is. Vengeance. The advantage of it lies in how effective of a tactic it is at scaring evil. The disadvantage is overkill, taking things too far, when sometimes the punishment may not seem to fit the crime.
The Earth Aspect- This one makes me think of a fair, balanced version of fighting evil. Reaping what you sew. Since this planet Earth consists of all 4 aspects, any of the other 3 aspects can be applied where necessary. Justice. The advantage is that it's actions are equal to the evil it's attempting to fight, destroy, punish, or teach a lesson to. Not too much as to be considered unfair, yet not too little as to be considered weak and afraid to fight back. This one I feel most in line with, because I understand and accept all of the aspects, but agree with this ideal the most.
The Water Aspect- To fight hatred with love, cruelty with kindness. It's advantage comes with the times it's able to make an evildoer see the error of their own ways by comparison to the seemingly undeserved respect you show towards them. As in, if you want an evil person to be good, then first show them what good is. The disadvantage is for the times it can be viewed upon as a weakness.
The Air Aspect- This one I can interpret in a few ways. The first way I thought of it, a while back, was ignoring evil. It's advantage is against the type of evil that thrives off the attention it's given. Ignoring those types of evil people make them lose the motivation to do evil. Another way I had interpreted it had to do with a combination of knowledge and indirectly fighting evil. Such as being a strategist or someone in a support role who may not necessarily fight evil themself, but yet in a sense indirectly does by offering some type of advice or useful resource to help the other person fight evil. Praying could perhaps be considered this as well, yet supplemented with the intentions of any of the other 3 aspects.
Each of those 4 represent common tactics you see with Police, when interrogating people. The Good Cop (Water), The Bad Cop (Fire), That one Cop who is serious, can be friendly but also firm and strict (Earth), then there's that one quiet Cop that you don't know what they're thinking (Air).
One mistake I see certain Warriors make is denying the importance of aspects other than their own, rather than learning to balance out those other ones.
There are also mixtures of these elements as well, such as Lava, Ice, Mud, Smoke.
