Yes, under the Constitution, the Federal government has very limited, enumerated powers.
The States are free to make bad laws or good laws or no laws.
Wife-beating, abortion, rape, clubbing baby seals, killing puppies, etc., might be evil things to do, but they are not Federal issues.
If you think the States are too unjust to handle these issues, then why stop at the Federal level? Shouldn't the U.N. make these decisions, because otherwise what if the U.S. legalized murder?
Unalienable rights are not given to people by states. Life is an unalienable right.
The Federal government should have little power over the vast majority of criminal cases. However, Congress was granted the power to define person under the 14th amendment. This would then force states to outlaw abortion. This is not a violation of the 10th amendment because the power was delegated to Congress to do this.
