Should I only praise the ones you approve of?
No, objective criteria are always preferable. Whatever he did or pledged to do for the SB, Wałęsa was in fact buoyed into a leaderhip role and becmae instrumental in toppling PRL. He actually wanted to end the Gdańsk Shipyard strike saiyng the govt had accepted the strikers' main demands but was overruled by the strike committee so the protest was continued. Schetyna can be praised for deciding to shift PO to the right to be more in line with the Polish nation's expectatioins, eschewing the libertine whackos who had tried to take over the party, Kijowski was a nobody suddenly vaulted into celebrtiy status which has gone to his head. At least he has a nice ponytail, if you like ponytails. Also, he is said to have finally come through with his arrears in child maintenance payments.
