The only true irony I find in this is that an abortion Doctor called himself a christian. But, to answer the question, no, Jesus di not approve. There are those that would argue Jesus does approve, but, biblically, neither man was right. All life is sacred in the eyes of Christ, hence His death to give life to all men.
In fact, God says in His word that vengence is His-He will re-pay. He also says the He is the Author And Finisher, only He has the authority to give and to take life.
That being said, some of that authority is delegated to the state, ie capital punishment. He also charges a man to defend his family as the provider and protector. If the state ever usurps that authority and makes it mandatory to kill all unborn babies, a man defending his family would be justified.
