concurring specially.
I concur but am compelled to point out that conviction of crime and incarceration alone, even repeated, would not be sufficient in and of itself to warrant termination of parental rights. Legal termination of the parent-child relationship cannot be used as additional punishment or as conclusive evidence that termination is in the best interest of the child, under OCGA § 15-11-81. See In the Interest of H. L. T., 164 Ga. App. 517 (298 SE2d 33) (1982).
