Vince had the man state that he did it for ego and people are still fighting this
It should've been clear when he rejected Gretchen and Elliot's offer in season 1, the instance Vince says Walt broke bad, to see that ego was driving this. When he was out the game, saw someone else buying meth supplies and confronted them in the parking lot, telling them to get out his territory, it should've been clear that ego was driving this.
Were we supposed to get shots of people in Germany and the UK high on meth?
Dude was being mentioned on Charlie Rose. Billionaires were donating millions to charities just to remove the stain his name put on the company he hasn't had a part in for 20+ yeas. His old house became a tourist attraction. I think it's apparent how the public would react to a high school chemistry teacher becoming a drug lord.
We saw the damage when Walt went to the crack house to get Jesse how the shyt affected people. When Jesse OD's, her father loses his mind and planes collide, we were seeing the impact of Walt's actions.
We've seen his legacy. We don't need an Independence Day montage of reaction shots to see how meth fukks up communities.
Walt was on a team that won the Nobel Prize in chemistry, made 98% pure meth, is creating that contraption really far fetched?
