My question is, will neutering cure the problem dog of these independent

his life, and will he carry these tendencies with him until he gets a
few years older and settles down?

If he'd been in the wild, I would expect him to be shy and
frightened of humans. He sounds like a dumped dog, not a feral one.

In any event, I think your best bet is to neuter him and rehome him
with someone who will obedience train him and make an indoor pet of
him. Letting him roam is just asking for trouble. At the very
least, neuter him if you intend to let him roam. It may not stop
him from running off, but it *will* stop him from fathering any more
unwanted puppies.
