Threats are also used by our own justice systems to get people to obey the law. And not threats but rather warnings are used by God to remind people that there is indeed consequences of sin and they aren't pretty.

You may not like being reminded that there are consequences to sin, but there are.
If you think it is a sin not to agree with you, then welcome to the wonderful world of mental illness.
