Destroy, in the biblical sense, is equivalent to punish and torment for all eternity. The soul, being immortal, experiences “death” when separated from the body, “death” when separated from their first estate and plunged into a new sin nature, and “death” when separated from the presence of God.
And most importantly, the soul is definitely no immortal. It very clearly teaches in matthew 10:28 that He can kill both body and soul. What is eternal is the spirit you receive when you are born again.
Son, you already have a spirit that will exist ‘forever’. What you need to do is find out if your spirit will go on existing forever as a godless spirit or with HIS Spirit Life in your human spirit.
