1) The animals did die before Adam sinned. Adam saw this .. thus understood when he was told that if he ate that certain fruit .. he would die. Understanding what death was ... he was well aware of the results of his decision. The animals were not pets.
Adam and Eve were perfect creatures. They spoke with God.
Being imperfect today ... and obeying Jehovah must really make his heart glad.
To imply that Jehovah is doing something wrong is very dangerous. He who created ALL things should be relied on to see his work finished in proper order.
It is normal to question why man is allowed to suffer. Habakuk did also. Many in the Bible did. We must all rely on Jehovah fulfilling prophecy at the proper time. He will not be late and he will not be early.
