She has her own understandable motives but Skyler is one of the least sympathetic characters. She's awful from the start, goes on to do more selfish things, and is smart enough (unlike Marie) to be at least somewhat self-aware about it. Often she *chooses* to be terrible.

What do you mean, "goes on to do more selfish things" ? I don't recall much she did wrong, outside the context set in the first few episodes
