Another parable put he forth unto them, saying, The kingdom of heaven is likened unto a man which sowed good seed in his field: But while men slept, his enemy came and sowed tares among the wheat, and went his way.
( Matthew 13:24-25 )
The purpose of creation is to give life with free will to all souls. God created companions to fellowship with, but he is not going to force anyone to spend eternity with him. You have the free will to choose.
