My best friend Luca let me down, should I give him a second chance?
From the analysis of the tarot it seems that your best friend Luca is not in a good physical, emotional and spiritual state. So, considering all of that, the answer to your question should be: No, you shouldn't give him a second chance. The reason is that Luca may not be able to adequately handle the situation due to his current physical, emotional and spiritual state.
