Is the Death Penalty ok?

A Kansas court just ruled death on Lisa Montgomery, for stealing an unborn baby from a woman's womb and then murdering her. In 2004 Montgomery met Bobbie Jo Stinett at a dog show and planned from then to kidnapp her child. Montgomery kept in touch with Stinett online and planned to meet with her again to purchase a puppy. The prosecutor proved that Motgomery planned this attack because she had been researching on how to perform a c-section. She had been in trouble before for faking pregnancies to reap financial benefits. This premeditated murder is a result of Montgomery's ex-husband threatening to expose those lies to her work. She broke into Stinett's home, tied her up and tried to perform a c-section. She was able to retrieve the baby and then killed Stinett. Montogomery was seen showing off the baby as if it was hers in her town Melvern, Kansas. The baby was born 4 weeks premature, yet Montgomery did not try to get medical attention for the baby. The baby, Victoria Jo , is three years old now and lives with her father. As for Montgomery, she is now on death row awaiting her fate for this heinous crime. I am personally against death row because i don't think that anyone has the right to kill someone else, but I don't know what the proper sentencing is for someone like this. Yes, I think she is mentally ill however, that seems too easy to let her sit in a mental institution. What do you'll think?
