There's a lot of freedom at first as a soldier to realize that you could put down so much evil in the world until you realize you might actually be putting evil into the world.
No, there isn't. At all. What so ever. A soldier is merely a tool by a state that may or may not (and historically NOT) have good intentions.
A soldier is first and foremost instructed to FOLLOW ORDERS. Not because of some nefarious plot to use people, but because doubt on the battlefield can mean a weakness ripe for exploitation, and can introduce delays that mean defeat.
That's a very cynical view. Their country is their master, if they got invaded, like Ukraine do, then them fighting for their master(or country, if you will) is fighting for freedom.
I mean, there are soldiers fighting for their countries' safety today! They're just not the ones thousands of kilometres away from home (they might be piloting drones on the other side of the world, I guess, lol), of course.
Naw man as a soldier you will be told to do your tiny part of a tiny task. No kidding that part may just be, take that water tank over there and wait until told what to do.
If you're one of those brave dudes trying to hit aircraft with old rocket launchers while sprinting in your flipflops, you're almost certainly putting down evil, sure.
