For my first playthrough, I'm planning to play stealthily. I won't run and gun cause mayhem, but sneak around and take people down without alerting anyone. I've noticed when grabbing people, I have the option of doing a lethal, or non-lethal takedown.
Is there any reason why I would want to choose the non-lethal option?
I could utilize silent (and lethal) weapons and that will make things easy, but why would I want to go slower and stay non-lethal (other than for challenge)? Are there any perks that could level up staying non-lethal? Will I be able to turn the enemies later in the game for whatever reason? Will a boss character be more sympathetic to me if I left their minions alive? Or will I gain anything by ensuring everyone dies?

There are numerous missions (both story and side missions) that want you to go in silently and not kill anybody. These missions can still be completed loud but may have a different outcome - in the instances of side jobs this normally means you're missing out on a bonus payment for completing the job how the fixer wanted it fixing.
There are also numerous instances where killing somebody is then bought up later in conversation (as both a positive and a negative, depending on the conversation you're having) however this does not have a final impact on the endings available to you.
