If a second conscious head grew out of your shoulders, should you have the right to chop it off?

Okay.

OT: Since I am Pro-Choice for abortion, I think he should be able to make the decision to detach the head from his shoulder. There was a possibility of a head growing out of his shoulder, not a complete and solid outcome. 

Also, if the head needs to take nutrients from his body, then his lifestyle would change. (This is directed at the person who said it's different from having a baby since having a baby changes your lifestyle.)
