|The fact that you are questioning the assemblage of characters may be a sign that it is unbalanced.|
Alternatively, it could be a sign that you are writing something close enough to the real issue to make you feel uncomfortable.
People pay good money to feel things when they read. If your writing makes you feel things, then it is important to explore that as it will make it easier for you to do the same for your readers.
As a case in point, I recently wrote a first draft of a scene that I wouldn't even let my wife look at... but when I had reworked it, toned it down, crystallised the key story point etc. I was confident to read it out to my writing group and the constrained power from squashing such a big idea into something that I could allow myself to be associated with made it into a very effective piece of writing.
Cherish your doubts.
What one of the contributors to a thread I had on the same subject said was to look at what it is that is making you feel uncomfortable and to decide whether it is just inflammatory or actually key to the story. If it is inflammatory or otherwise gratuitous, cut it. If it is key to the story, write it clearly and without shame.
Nabokov wrote about a paedophile, but wasn't one.
"Silence of the lambs" describes a cannibal, but the author hasn't been convicted.
JK Rowling wrote about a magical community who have at intervals killed each other in a variety of unpleasant manners. I don't think she's one of those either.<Added>

Sorry to say, but this undermines the whole business model of the industry you're trying to get into!
Start with people you trust, but always work towards a point where you are ready to present it to the world at large.
