The Godhead planned this action out; as One. God the Father, God the Son, and God the Holy Spirit chose to have God the Son (Jesus) come to earth, become a man, live (as a man), teach mankind how to live and then become the sacrifice that His (the Godhead’s) righteousness required for payment of our sin For the wages which sin pays is death, but the [bountiful] free gift of God is eternal life through (in union with) Jesus Christ our Lord. Romans 6: 23 (Amplified Bible)
Then this amounts to some pretty poor planning on his (God's) part.
All spirit beings will exist for all of eternity; either in ‘Life’ with God or in ‘Death’ without (separated from) God.
Except it's not that simple is it? It's not just a separation from God. That would actually make sense and would be something that we could attribute to a loving, caring and compassionate God. But no, God's plan does not just include a separation, his plan involves eternal torment (torture) for those that fail to accept his "gift".
