Why Lupin¡¦s father offered him to a wicked werewolf?

It arouses me a lot of curiosity when Lupin told Harry in the Chapter 
¡§Very Frosty Christmas¡¨ (don¡¦t have to book right now to
turn to the 
page, sorry¡K) that in fact his father ¡§had offered¡¨
Greyback, the 
wicked werewolf, to bit the little boy Lupin and turned the latter to 
be one of them. 

Under what circumstances would a father lead his own son for such a 
miserable life? I could not resist feeling resented and irritated for 
Lupin¡¦s father when I was reading. I just can¡¦t imagine a
good reason 
that back up his unforgivable act. Do you come up with any theories?
