Why Does Spoil Mean BOTH "Rob Blind" AND "Give Too Many Presents-to"?

[mythociate]

I remember when I was young, my father's parents would buy me nice gifts, but would say they were worried about "spoiling me."

Then I read in the Old Testament how Israel would frequently "spoil" the enemies they invaded (robbing them blind upon conquest).

Are the two meanings linked somehow?

I imagine my grandparents might've thought they were 'robbing me' of the appreciation for the value of a hard-earned penny ...

But don't get me started on 'spoiled GROCERIES!' :barf::sick:
