All addicts have self destruct buttons.
They don’t care about anything else apart from where their next drink or fix is coming from.
They don’t care about their families, friends, loved ones etc. They are destructive. They destroy themselves first and foremost, but they also destroy their nearest and dearest.
If anyone who is an addict really cared more for their wives, lovers, children, parents, friends, than they did themselves, they would give up their addiction.
