We never learn.
In the right (or wrong) hands, benevolent plans can easily be put to malevolent purposes.
Even the most well-intentioned government law or program can be—and has been—perverted, corrupted and used to advance illegitimate purposes once profit and power are added to the equation.
The war on terror, the war on drugs, the war on illegal immigration, asset forfeiture schemes, road safety schemes, school safety schemes, eminent domain: all of these programs started out as legitimate responses to pressing concerns and have since become weapons of compliance and control in the police state's hands.
Mark my words: gun control legislation, especially in the form of red flag gun laws, which allow the police to remove guns from people suspected of being threats, will only add to the government's power.
