I personally believe that the norm is:
"What goes around, comes around."
Galatians 6:7 (New International Version)
Do not be deceived: God cannot be mocked. A man reaps what he sows.
But there are exceptions to the norm:
"Bad things happen to good people."
1 Peter 2:22-23
22 "He committed no sin, and no deceit was found in his mouth." 23 When they hurled their insults at him, he did not retaliate; when he suffered, he made no threats. Instead, he entrusted himself to him who judges justly.
Agree. "What goes around, comes around" is right out of Proverbs 26:27:
"Whoever digs a pit will fall into it,
And he who rolls a stone will have it roll back on him."
