Ben Sisko lost all credibility as a father in What you leave behind

For seven seasons we saw Ben Sisko stand up and be counted as a great but human father to Jake. From the first episode where we meet them on the holodeck in the covered bridge we were shown “he will do anything to be there for Jake.”

Which would be fantastic except for the rugpull on the last episode. Cassidy is pregnant with his second child and he leaves. Just leaves. He leaves to be with the wormhole aliens. To me everything that we were lead to understand about him was a farce.
