Belief in divine decree can protect a person from panic and excessive fear of others. It is not a license to avoid responsibility.
An important difference
1. Facing hardship with prayer, lawful precautions and patience.
2. Injuring someone, then saying that decree excuses the injury.
The first joins trust and responsibility. The second misuses the concept of decree to evade accountability. Harm to life, property or dignity still has moral and legal consequences.
