After reading this topic, two sentences jumped out at me.
You start by asking
Is it moral to kill when a cure option(or cure options are/ is)available?
This brings up the issue of what morality is...for believers and non believers alike.
You end the topic by asking
Is it moral for God to kill when a cure option(or cure options) is available?
Does your God need to have good morals or does it matter?
Thus I am assuming this topic to be addressed only to believers in God....am I right?
