Learning is what Walter did his whole life. He needed to learn, to have contingencies. When you have a death sentence hanging above your head, contingencies stop to matter.
Walter truly only learned. But Heisenberg no longer cared about it. Walter was a genius chemist. You become that by learning every possible second. Walter learned. Heisenberg? He just did.
That’s the issue. It’s someone else’s fault, always. It requires a substantial amount of grey matter to accept personal responsibility, e.g. “I fucked up”. It was me, who made a mistake. When we make a mistake we downgrade to our lowest, most childish behavior, to deceive, lie and cheat, just so we are not in trouble.
Some people never ever ever ask the question to themselves “Did my actions cause harm to another?”. Their self-importance is too great for that. The maximum I can ever hope for, with the current state of humanity is, they’ll think about it, but throw in a nice excuse. Usually “But I was stressed/busy/angry when I did it”. And that makes it okay.
So, sadly, it requires a lot of grey matter to not use it. Mainly because of humankind’s inability to accept personal responsibility, not because a clanker contains some unobtainable information.
