Good: soldiers
Bad: soliders

Here is another word that keeps messing me up. But I just noticed the word inside a word. It might help me in future spelling. The word is SOLD. Don’t SOLDiers go to war because they are selling the ideals of their nation to the enemy? Maybe some armies wish to keep the civilians of their country free from enslavement.

Another set of SOLDiers may wish to subject their enemies to be under their control. Each has a theology and thus SOLDiers are the instruments of promoting that theology against those who disagree.
