ethically and morally it is always wrong to take another human beings life including your own.
simply, because we are wasting what nature and the process of natural selection has granted us.
based on the same principle it is ethically and morally wrong not to recycle and preserve what precious little earth has left.
Now, two angles to look at my specific example,
first, terminal cancer means I die anyway no matter what i do i cannot avoid it, second, the SUB HUMAN VERMIN that run the state of affairs in my country ( i don't know if you call iran your country too so i use the term my country) are not ethical or have any sort morals, they cannot even be classified as amoral, so when dealing with such situations and systems IT IS HIGHLY ETHICAL AND ONLY MORAL to put aside all your ethics and morals and go all out to annihilate any signature of them on earth.
if you don't you are being unethical and selfish towards younger and future generations of iranians and human beings because you are allowing these THINGS to keep inflicting their syphillis on them too.
