As great as some of Walt’s ploys are, Mike is the biggest outright badass on this show, though Hank certainly gave him some competition in One Minute.
"Moral of the story is: I chose a half measure when I should’ve gone all the way. I’ll never make that mistake again. No more half measures, Walter."
Here’s a link to Mike’s full speech. I love how even the secondary characters get a piece of the spectacular writing, and the actors sell it perfectly.
