Advantage Satan?

Q.The Bible identifies two possible roads, one broad that is followed by many and leads to death and the other a narrow road followed by few and leads to life.  Seeing that the Lord does not want any to be lost does this not mean some sort of advantage to Satan if he ends up with the most souls or is quality more important than quantity in this case.  Thank you for your invaluable guidance in these times that we live in,may the Lord bless and keep you.

A. This is not a contest where the outcome is in doubt.  Satan has already been defeated. He can not gain any advantage because Jesus won the victory at the cross.  The only remaining question is how many humans will join him in that victory.  Most observers have concluded that many more will side with Satan than with God.  While God desires that none should perish but for all to come to repentance, (2 Peter 3:9)  He has given us the right to determine our own destiny (John 3:16).
