Can you talk in any more detail about what it is that they were doing and how it was that you pushed them out? It seems like decisions like that are drastic and would necessarily involve tons of thought and deliberation as to whether or not that could potentially be viewed positively or negatively.

And truly only you can answer the question as to why you were doing something. At least you could boil it down into perhaps "What you thought" was going to happen, rather than perhaps alternatively "What you wanted to happen". Because that could be potentially an excuse for a mistake, which I don't think would then warrant a positive spin on the mistake. Mistakes must always be learned from, and you should never make serious enough mistakes that endangers the well being of other humans.
