I feel awful for that "bad male cat" and the mom, and the poor kittens that will be born.

Here's an idea. Go on the internet and SEARCH for information. Considering you have many little lives on your irresponsible hands I'd recommend you get as much information as possible asap.

When these cats are born SPAY the mother and make sure you find good homes for the kittens. Do not give them away for free, and don’t drop them off somewhere to be killed. Interview each and every family and make sure you get them all perfect homes.
