Yes you can. It's just that you do not like the idea.
Calling for help is doing something.
If you do in fact happen to "do what's right" in most circumstances, any adverse consequences, "whatever they might be", will likely be confined to physical harm to yourself, inflicted perhaps by the criminal, or possibly by an armed citizen or arriving first responder.
There is one BIG exception: if you intervene in what turns out to be a domestic violence situation, it is extremely likely that both or all participants will end up testifying against you, leaving you without a leg to stand on.
And, of course, unless you know the apparent victim, you have little or no way of knowing just what is "right" in the first place.
That you did what seemed to be the right thing at the time will not help you at all if you turned out to be wrong. And that happens all the time.
All downside and no upside.
