Objects or symbols can be cursed to various degrees according to the item itself, its origins and history and connections to certain people or places. Also according to its perceived value to the owner and the level of idolatry involved. Things can be particularly cursed if they are directly idolatrous, or directly connected with or used in idolatry. Or if somehow profane or unholy, or directly or indirectly connected with evil, the devil and Satanism, witchcraft, etc.
Even if someone did not know that objects – or symbols – were cursed or did not know they had them in their home or garden, or in their workplace, or even garage or transport, they can still be used by the demonic just the same. Although there would likely be a difference in the degree to which they are able to be used, which can be, for example, according to how much an object was valued or revered, or not. We can test ourselves whether we have the strength to let something go.
The degree to which something is cursed would also depend on what sort of belief system or value system is attached to them and the degree to which it is in conflict with what the Bible says.
