If view or pure function doesn't cost any gas, would they be abused?

So if I understand this correctly, view function only read data from ethereum and doesn't mutate any state and pure function doesn't even read data and they are intended for cases like return 1+1;
If this is the case, would they be abused since they don't cost any gas? Like could I just use them for free computation? What happen if I have a infinite loop in a view or pure function?

pure and view functions only are "free" when you call them externally, as in you call that function by itself and run the calculation on your node. So if you had a function that returned "1+1", yes you can call that individual view function as many times as you want for free, even without creating a transaction.
However, if you use a view or pure function within an internal function which DOES cost gas, you will be charged for those calculations like normal.

Just to add to @Shawn's good answer.
Yes, you can abuse them. But as the pure and view computations are performed only on your own node you would only hurt your own node. You would not hurt the Ethereum network in any way. If you call the function(s) enough, you might even crash your node but it still wouldn't hurt the network in any way.
