Ultimately it's their country, their rules and regulations.
These two and the others on death row broke those laws and will be punished to the fullest extent of Indonesian law. If you don't like it, don't visit the country. If other people who live there don't like it, then they damn sure better not break the law otherwise they could be on the same path.
These two deserve no sympathy at all, they knew the risks and broke a law with a very serious consequence. They have paid the ultimate price for it and now it's time to move on.
Unusual to see such a spirited defense of Sharia Law. Congrats on your open mindedness.
