“Having the worst parents is not an excuse to do the same thing to your child.
If you can become better, then why not.”
Just because you have bad/worst parents, that doesn’t mean you need to repeat the circle.
If you can break the wheel, and start anew, to be better husband/wife, to be better father/mother, for your children and family, if you can doing that, then why not.
If what you want is a happy family, both inside and outside.
