Difference between 'take' and 'steal' w.r.t. kidnapping

Solution 1:

Stolen has within it's meaning that:

The thing wasn't yours to take.

The object (or being) was (usually) taken in stealth.

With "taken" the same meaning is forced:

You can steal a cookie, (that you weren't supposed to take, when nobody is looking) but, if you take a cookie - it may have been offered to you from a plate, in front of a group of people.
