If Johnny didn't get addicted, things would have turned out differently.
That bitch Ashley killed Johnny, not Trevor. She got Johnny hooked on meth again.
"A brother might stab you in the back, a woman certainly will, but a bike will never let you down." He just went against his own words.
I smell bullsh*t.
He also said that he would never be hooked on meth again. We all know how that turned out.
He did go against his own words, all for a whore who also happens to be a meth addict.
He never had a chance. The meth turned him into a weak person.
Johnny was also stupid, since he didn't bring any back-up.
But, on track, the meth turned him. Another example would be Marnie, who went from heroin addict to a clean person, who has moved on from drugs, but she obviously improved her life, unlike Johnny, who returned to his addiction, instead of moving on.
