I think it doesn't make them a 'bad person' because people are always capable of changing (even if it only happens once in a while). And it doesn't make them a bad person because our actions are mostly a reaction to our environment, and we don't always have a correct/full view of it to begin with.
So, applying your judgments to a person who reacts to their environment based on limited information and experiences, and saying they are fundamentally good or bad may not be totally logical.
Then the saying "only God can judge" means that an omnipotent being, who perfectly understands everything, is the only being capable of perfect judgments and certain condemnation or praise.
