I am always willing to explore hypothetical problems. Actually, I think that they are great tools to find out a lot about ourselves. So, let’s explore your stipulated scenario.
You created all those “beings” for the sole purpose that they would love you - freely and without being programmed to do it. No problems here. But your thought experiment is not “fleshed” out. There is this island, and there are those “beings”. All of a sudden a disaster strikes, for example a hurricane. What are you going to do? Will you come to their aid, and help them? Or will you stay behind the walls of your hypothetical dwelling, and observe their trials and tribulations without showing your love for them?
Why would you expect them to love you, if you are not willing to show your love to them? Love is not a give-and-take, a tit-for-tat, but if you just sit in your ivory castle, and do not offer the signs of YOUR love for them, then why would you expect them to love you?
Maybe you say: “I already showed my love, by creating you, and that is enough”. But it is not. Life, existence - in and of itself - is neither good nor bad. A good, pleasant, fun-filled life would be good, but a painful, misery-filled life is not good.
If he wants to be loved, then he should show his love for us, unmistakably and clearly. Since he does not, he does not deserve to be loved (Jesus and his unnecessary “self-sacrifice” notwithstanding).
