Many reviewers here either doesn't understand english properly or didn't follow the story properly.. In the course of movie, heisenberg never killed anyone out of will but to save him self.. And most importantly at his dying years he still cared for his children harming no one except someone trying to kill him. Drug thing, whether you do or not, it still doesn't change.. It's all illegall all over the world but is drug deal reduced? not an inch, it's infact compounded 100 times since several 100 years.. So this movie is not about all drugs but about helping family out of desperation..
