Mankind has freewill.

A criminal is somebody who believes that they have an inalienable right to mess with or even ruin your life and may use the addictions you have not given them as an excuse.
They are not: merely products of a bad upbringing, victims of abuse, misunderstood, simple, basically good at heart et al ad nauseam.
Some of these to some degree - perhaps! But we live in a society wherein nobody needs to steal bread to live.
Every criminal bar none has freewill. Every criminal has made a conscious choice to interfere with somebody else's comfort zone. Virtually every criminal acts from the basest of motives and ultimately, every one personifies selfishness.
Some 'grow out of crime' as they age - many have made a conscious lifestyle choice.
Consider burglary. The crime is mean and utterly contemptible - yet it attracts token sentences in court.
Rehabilitation? - Yes, of course, please, but punishment appropriate to the crime first is a must.
