I got married because I loved my wife and it was very important to her. If it wasn't then I wouldn't have done it. I'll never have children though because I know that I'd f**k up their lives just like my father. For that reason I wouldn't adopt either, however if I thought I would be a good parent I would adopt. I don't want to remarry after my wife, at least not yet.
I'd adopt so that I could give the child a chance in life - they didn't ask to be abandoned by their parents or to be orphaned and I'd like to give something back to the world.
