Yep cutting kids brains out and brainwashing them into killing machines is certainly the right thing to do.
Well his ultimate was to end war as a business in its entirety and restore individual freedom. He was trying to make it so there would no longer be a need for child soldiers in the future.
Besides, he's arguably more moral than Raiden given that at least the suffering he's inflicting has a noble end goal. Raiden just kills because he enjoys it, which is revealed before you fight Monsoon when you hear the last thoughts of all of PMCs you're slaughtering.
Even the song lyrics during the final boss battle hints that the battle is much greyer than Raiden may think.
Standing here
I realize
You are just like me
Trying to make history
But who?s to judge
The right from wrong
When our guard is down
I think we?ll both agree
That violence breeds violence
But in the end it has to be this way
I?ve carved my own path
You followed your wrath
But maybe we?re both the same
The world has turned
And so many have burned
But nobody is to blame
Yet staring across this barren wasted land
I feel new life will be born
Beneath the blood stained sand
Beneath the blood stained sand
The Senator at least had the good grace to recognize that others might be right instead of Raiden's "rawr everyone in my way is wrong"-attitude.
