I think the way Echo is written is usually the best way to write convincing spy characters. You keep such a character mysterious and leave the door open that she can flip sides any time. If you write a predictable spy character and explore all of her back story, it takes away the point of such a character.

If they had shown us some good backstory to convince us that Echo is a good person who deserves Bellamy, it would have made her so predictable and boring. Her being able to make tough calls like betraying Raven, plotting to kill Shaw etc wouldn't have been as valuable if we knew her inside and out.

Now that she's proven herself, the writers can now dig in to explore her backstory. And honestly speaking, Echo spying and cheating isn't as bad as what Clarke and Bellamy have done before in the name of protecting their people. So, they should be the last people to judge her.
