K'ritot 2a says there are 36 transgressions for which the punishment is karet and provides a list (including idol-worship, various sexual transgressions, eating chametz on Pesach, desecrating Shabbat, and a bunch more). At least some of these would be punished by a beit din with death (if you had witnesses, warning, etc); the torah provides an example with the Shabbat wood-gatherer. Is that true of everything on this list? For example, could someone in principle be sentenced to death for eating chametz on Pesach?
Noticably absent from the list in the mishna is murder. The torah provides for that with the cities of refuge and the possibility of death at the hand of heaven, which seems to be different from karet because it's not on this list. Are there any other death-penalty transgressions that are not punishable by karet?
My question is: with the exception of murder, are karet offenses and capital offenses the same list?
