Yes, by using Photo Library, deleting a photo from my phone, will automatically delete it from iCloud. As I said above, "device-size versions are kept on your device" so it will save you space on your phone. If you really want to delete the photos on your phone, perhaps the safest way to back them up is to transfer them to your computer:
Import photos and videos from your iPhone, iPad, or iPod touch - Apple Support
My understanding is that Apple intends iCloud to be a syncing/backup system and not used simply for external storage.
