If Zelda marries Link , Should they have a Child Together ?

Yes I think they should have a child. I think it will be a boy if they ever have a child.

no bc if they had kids and Zelda get captured AGAIN, then who will watch the kids? link is the only brave soul to go out and rescue her

I Believe yes, because every hero should have a decedent to carry out the duties of the Deceased Hero, If Link died
