WE all do at times, even the evil do I am sure.
however no one "gets" away with anything, it may seem that way, but do we know what is going on behind closed doors, not really.
For every action there is a reaction and consequences they will suffer
Look at OJ Simpson, everyone knows he is guilty as sin, (jury must of been bought) however God has his reason for his acquittal. HE was out laughing and having a good ole time, bang he sure is sorry now isnt he.
Same with Casey Anthony, I know in my gut she killed that poor little girl of hers and so do a lot of others agree with me. (once again bad jury but reason for it) her lesson is not over. I left a link to her update. Trust me your past comes back to haunt you. who makes sure of it, the one and only powerful God.
But it is maddening to answer you question.
So yes we all feel like that at times but trust there is a hidden message behind why they do what they do.
