Am i a murderer ???

All the people who are non vegetarians are murderers in some way including me. if so i should be a very big murderer. Being non veg is not wrong. But many time i have thought when getting killed how much an animal should be suffering? An animal also a creature like us. When cutting it must be also having the same pain. If a small blade cut how much it is paining for us. So how much it must be paining for that animal. 

But When eating we (I) do not feel it. As i said many times i have thought how much it must be suffering. But while eating when seeing the taste all the thoughts gone. Its difficult to be a veg even for a day. When a bird or a animal is injured or if with some sick most of us will feel sad. Even if a small injured & when it is bleeding we feel sad a lot. sometimes i cry also. But cannot think a logic why that same feeling not coming when eating the same animal & also cutting with the purpose of eating. 

Just for an example if we keep a Hen at home as a pet even if it is bit injured we may feel sad. If some one ask to cut & eat we will never let to do. But same time we will eat chicken which has been cut by some one else some where. What to do.. that cannot be changed. Next time when eating i also forget what i said now & will nicely taste it & eat :( .

Thats how our same mind changing according to situations. Not only in this matter most of the time we do the same. If something for us we feel a lot. But for others we do not care.

I have never thought about plants. After reading the above post my friend is the person who send me the below link. according to that plans also have life & they also can suffer like as. It can be. coz all the things which have life have feelings too.

One persons happiness consists the sadness of another person.
