Play from the blinds: J8s

[player1]

instead of J8s, is it correct to fold if:

-he had J8o?
-the BB is 50, or 100, or 150, or ...

thanks,

jc,
he is in the Big Blind which means it is FREE for him to see a flop with ANY 2 cards. Doesn't costs any money.

in my previous post, i mistakenly assumed that he was the SB and came up with a question based on that. i guess my question has more to do with which hands in general to complete with from the SB and if the current level should factor in. (ex: BB=30 vs. BB=150)
