Can I be a helpol and a witch simultaneously?

I've been a helpol for a while and the religion has really helped me with a lot. From the simplest things like confidence and even got me out of some addictions. It's been wonderful so far. However, I've noticed that some people here have some "distaste" for the witches who worship Hellenic gods, and I suppose it is because they do little to no actual research about the deities and might sound disrespectful to who actually studies, but I'm not sure. Okay, so, I've been interested on witchcraft for a few weeks now and I want to know if I can practice both? Or Hellenism really can't go with Witchcraft?
