Nah Fring was running a massive nationwide methlab with cartel connection like a swiss watch for years prior with no issues and Walt just had to rock the boat.
Imagine willingly getting involved in that shit and trying to rock the boat.....
Beyond retarded in its own way....
Honestly cant even begin to describe what kinda piece of retarded shit you are to kill someone after you robbed them and they complied...while begging they have kids...
Turn a robbery into a murder....over nothing.....
You look them dead in the eye and tell them "im gonna name you in my suicide note" then walk away and go home for the day.
Let them stew on it for a bit.
Ever wonder why the higherups dont understand about "time with the family", this is why.....
They will throw their kid out the window for the job and you want to go watch Jimmy play football.......
FYI IF a dude whos twice your size hits you like that, your basically justified to do whatever you need to to defend yourself, IF you "feared for your life".
