If it is out of cold blood and not needed firstly, It is wrong because you stopped that person living out his life. Life is precious and once lost that specific life is gone for good. It would cause sadness, heartbreak pain and mourning to the loved ones of the victim. It is wrong for the same reason why you wouldent like somebody to murder your children or parents, it causes pain from loss.
It is traumatic for the victim and can cause mental/physical pain and suffering which is wrong because when somebody feels that pain it can even tuin there futures and create a very timmid and scared exitence for the person, again it is wrong because it spreads pain and suffering which can ruin peoples lives.
Stealing to save your own life from starvation if it does not cause suffering to others could be seen as acceptable, especialy as animals have to by nature survive at all costs, but if you steal an old womans pension money or something, it would obviously cause her much distress and also maybe suffering. It could make the persons life much worse depending on what you take from them, especialy if it was something they need for sheer survival.
Causing people mental and physical pain while they are defeneless is a horrible experience and would be traumatic for the individual, again like rape and other things it can seriously ruin peoples lives and cause suffering pain and disscomfort in all degrees and levels. causing people to go through this type of treatment is negative not positive, put your family members in the shoes of the victim to get a better perspective of why that pain and suffering is negative and wrong.
See tourture and rape for a simular discription.
See murder for a simular discription, but X it by the number of victims and + the impact of the suffering on a trickle down effect.
peace.
