Should I use scripts in this case?

I am writing a game. this is in C ++ direct x, and I think I'm creating my own engine, as I program with winproc.

I have achieved great success, such as sound, collision detection, AI, specific to my game settings, creating dynamic graphics from tiles.

after some research on event programming, I was told "script it". I investigated this, and as far as I can see, the script is used so that non-programmers can add to the project.

I am a good programmer, and I am not going to work on the game anyone else, except for external things, such as graphics or map design. I already had a function where I can read maps of csv files. they contain not only the layout of the tiles, but also npc data, inputs / outputs. other files of the same control monster and element data, so I can update the contents without recompiling.

So, I ask you to look at experienced programmers and maybe real examples that relate to my circumstances as to why I should or should not use scripts in my game?
