Smallville viewers: What's up with Lionel Luther?

[Nocturnal]

Is he good or bad? From watching last night it seems like he's bad. However, others are speculating that he is doing this for Clark's own well being. Imagine if Lex found out and Lana left and Lex went full blown crazy... could that be way Lionel did what he did? If not, explain.

I think hes good up to a point. But he will get killed off sometime soon.

 

[Motek]

He is a Luthor...

Says enough.
