What makes stealing property wrong is that it is detrimental to life. Life being the ‘standard’ of what is good (improves life) or evil (destroys life). It harms the life of the individual who has lost their property and society overall as others decide not to create or own property on the basis it will only be taken from them. Only civilised societies recognise this, essentially individualist capitalist societies. When this is not occurring, query the society you live in.
