Both letters of Peter deal with suffering for doing good in Christ’s name. Peter commends suffering for doing good as a great trstimony and condemns suffering for doing evil and being punished for it by authorities.
Is there merit in suffering for doing more than our Lord requires? Sure, among other blessings, it increases our faith as Jesus pointed out in Luke when asked about increasing faith. Mountains into the sea aren’t the result of doing one’s expected duty.
Christ paid the penalty in full so we didn’t have to.
That includes the suffering for sin.
