The following argument has been numbered already. To indicate the important features of correct argumentation please use the numbers to draw an arrow diagram that accurately reflects the flow of the argument.(1) It is morally wrong to abolish the insanity defence against criminal responsibility as some nations have done recently. It is wrong because (2) people who are insane cannot be held responsible for their actions and (3) it is wrong to punish someone who is not morally responsible for a criminal act. Besides that (4) it is absolutely useless to punish those who are insane since (5) their punishment would have no deterrent effect whatsoever. (6) Those who are mentally sane would not be deterred by it and (7) neither would those who are insane be deterred by it in any way. And last but not least (8) abolishing the insanity defence would lead to increasingly overcrowded prisons since (9) those who would otherwise be put in a mental hospital will now be put in the normal prisons.
