Should someone who conspires to commit murder get the same sentence as the hitman?

I'm posing this question due to the recent release of Ray Carruth. He was a former Carolina Panthers player who hired a human to kill his pregnant girlfriend in 1999-- because he didn't want to pay child support. Carruth's girlfriend died hours later, but doctors were able to save her son. He was born at 27 weeks old and he has cerebral palsy due to a loss of oxygen caused by the shooting. The boy's grandmother has been taking care of him for all these years. Carruth was just released yesterday after serving 19 years (he's 44 years old now). Meanwhile, the man who pulled the trigger has 35-40 years left in his sentence and don't be released until he's 75.

Do you think a conspirator to murder deserves the same sentence as the person who committed the crime?

In this case, I think It's wrong for Carruth to only serve 19 years when he's responsible for murder and his son has to live the rest of his life with disorder. I definitely think a conspirator to murder is just as responsible as the one who pulled the trigger.
