can a warm gun bring happiness to theTin Man?

i wonder if the Tin Man can really be happy to have a heart? well, in the story the Oz characters already had inside them what they desired. they just didnt realize it. The Tin Man wanted to ask for a heart when he was already someone caring and thoughtful. anyway, ive been thinking (for a long time. ive had this thought months ago i think), isnt the Tin Man better off not having a heart? he has a metal body, he wont be able to feel the warmth of another living creature (well, i assume that a metal body wont have the sense of touch as other living creatures). will it not be torture for the Tin Man to have a heart? to care for someone but not be able to feel a warm hug or a sweet kiss? can he say for the rest of his life that "its ok" and pretending it really is ok whenever he is asked whether his body can feel the joyous warmth of another living creature expressing their affection and appreciation. its like he can never be truly satisfied because he cant enjoy his heart as much as normal people do. a tin man isnt designed and built to have a heart. so the Tin Man shouldnt have asked for a heart. He should have asked for something in accordance with his nature. or asked that his nature be changed into something that is in accordance with having a heart. if thats not possible or too much to ask for then he should have settled for not having a heart at all. anyway, thats the Tin Man's problem, not mine. im just wondering if he can really be happy having a heart and a cold, unfeeling body.
