What's the difference when we say 幸せにさせる compared to 幸せにする?

I'm now confused between using させる and にする.

Can anyone please provide an in-depth explanation?

Difference between にさせる vs にする（as in 幸せにさせる vs 幸せにする)
…を幸せにする means “to make … happy.” させる is the causative form of する. Therefore:

> AがBを幸せにする: A makes B happy.  
>  XがAにBを幸せにさせる: X makes A make B happy.

However, some people may confuse these two and say 幸せにさせる when they mean
幸せにする.

answer
The correct one is 幸せにする, because する is usually the causative form of なる/である.

But it seems that when the object is a person, させる is often used instead of する
as a light verb.

```

    うれしくさせたい
    つらい思いをさせないで
    幸せな気持ちにさせる
    
```

する, なる, である, etc. are used in the active sense.

```

    好きにしろ
    つらい思いをする
    幸せな気持ちになりたい
    
```

So it is understandable that some people may say 幸せにさせる unconsciously.
