If god killed his only begotten son to forgive the sins of mankind. Why didn't he just kill the devil 🤔🤔

The sanctuary services given to Moses beautifully point to the entire crucifixion and ultimate sacrifice of  JESUS CHRIST  >> THE LAMB OF GOD , .>> Every animal sacrifice offered in the Old Testament tabernacle was a prophetic shadow pointing forward to the ultimate payment for the penalty of eternal death.  >> GOD  commanded Moses to build the earthly sanctuary so that humanity could understand the plan of salvation   >>Exodus 25:8  >> The entire sacrificial system served as a daily prophetic dramatization of the upcoming crucifixion of JESUS CHRIST  >>
The offering of animals in the earthly sanctuary was an expression of faith on the part of the people that JESUS > LAMB OF GOD  ,>>, would come and die to redeem them from sin. Therefore, the moment JESUS   died on the cross the shadow met the substance, and the typical service lost its meaning." >>>
When an innocent, unblemished lamb was slain on the altar, it represented the spotless character of CHRIST   bearing the sins of the world.  >>The exact timing of the crucifixion was perfectly synchronized with the sanctuary laws given by Moses. >> CHRIST   died on the cross at the literal hour of the evening Passover sacrifice.
Fifteen hundred years after this night,  JESUS  , the antitype of the paschal lamb, died upon the cross for the sins of the world. The lamb without blemish represented the spotless LAMB  OF  GOD >>> without the taint of sin... Type met antitype in the death of CHRIST  
John 1:29: "The next day John seeth JESUS     coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world." >>Luke 24:44: JESUS  HIMSELF  declared that the laws of Moses and the prophets pointed directly to his death:  >>>> "All things must be fulfilled, which  ****were written i n the law of Moses, and in the prophets, and in the psalms, concerning  ME  >>>"Romans 6:23: "For the wages of sin is death; but the gift of GOD   is eternal life through JESUS CHRIST  OUR  LORD  >>
1 Corinthians 5:7: "...For even CHRIST   our passover is sacrificed for us." >*. Those who accept the blood of the Lamb by faith are covered from GOD s final judgment, just as the Israelite homes painted with the lamb's blood were bypassed by the destroying angel. >>>Those who reject this ultimate sacrifice remain under the penalty of sin, which results in the ultimate "second" or eternal death.   >>
"Through CHRIST  alone   is   our pardon  to be  obtained. >> HIS   blood  will   protect  us from   >>>TO  DIE  FOR  EVER  IN OUR  SINS  >>>"I told you that you would die in your sins; if you do not believe that I AM  HE   , you will indeed die in your sins." >> JOHN 8  : 24  >>FOR THE MESSAGE OF THE CROSS IS FOOLISHNESS TO THOSE WHO ARE PERISHING, BUT TO US WHO ARE BEING SAVED IT IS THE POWER OF GOD." >> 1 CORINTHIANS  1 : 18  >>"perishing" are individuals who choose to depend entirely on human wisdom, pride, and intellectualism while rejecting the gospel.>>When people reject the love, mercy, and sacrifice that God offers on the cross, they willingly separate themselves from their only source of life and strength. >>the cross acts as a dividing line.>> The Dividing Line of the CROSS >>
FOOLISHNESS   OR  POWER   >>To those heading toward destruction,   >>>the message of the  CROSS   looks foolish; to those being saved, it is the active  >> POWER  OF GOD  !!!.!!
SALVATION  OR  DEATH   >>> Acceptance of CHRIST   s sacrifice brings eternal life,  >>>while rejecting it leaves a person in spiritual death and under judgment.  >>ROMANS  1  : 16   >> EPHESSIANS  2 : 16  >>  PHILIPPHIANS  2 ; 8   >> ROMANS  5 ; 8 - 9   >> ACTS  4 ; 12  >>>> quran  IS  A FALSE  book !!!....
