In relation to your question in the post, you among other people because you are unique and unrepeatable, just like each individual, we come to this world with a purpose, some discover what it is, others die without knowing it, sad but very true, they dedicate their lives to to bother others, to cause harm, but they pay for everything, KARMA takes care of it.
Another issue is that GOD grants us gifts, some discover what gift GOD gives them, others die without discovering it, but those of us who discover our gift, use it in our favor and in favor of others.
