A Decent Human.
The super-thin, long-haired father is decent man. It sucks he's addicted to meth because the viewer can tell he sincerely cares more for his family than the drug.
My father has been sober his entire life and he didn't give a crap for me. The meth father is by far a much better and understanding father. It's easy to slam him because he's a meth addict, but in the end, I can't help but notice that he is 10x the man my sober father was.
