Hello there!
It sounds to me like you don't understand how ram and recent apps work in android. My apologies if what I'm about to go into is redundant for you.
On android, unlike a traditional OS, MOST apps loaded into ram aren't active. They are in a suspended state that allows you or the system to access them faster. As a side note, this will also generally help with battery life. You usually don't have to worry about closing recent apps because when the system needs ram, it will free up ram for itself based upon chronological order of use. Leaving apps you use frequently suspended but ready to go really helps the system by not having to reload everything when you want to access it.
There is a saying for android that free ram is wasted ram. With the 3gb available on the Turbo, that can be a lot of wasted ram!
I myself have a hard time not habitually closing recent apps when I go through the list. But it's mostly unnecessary, and like I stated before, actually tends to work against the speed and function of the OS.
I used the terms like generally, usually and most, because sometimes you do have an app that doesn't properly suspend in the background. Sometimes this is based on function, sometimes this is because it's a poorly written app. These "rogue" apps can usually be spotted if looking at battery consumption. If you have an app you rarely access using much more battery than apps you use often, that may be an app you want to disable or end via the recent app list when you're finished using it. Going into the app details will also let you clear app data from the cache. That being said, they should be the minority of apps.
Hope this was helpful!
