why do some people think god is so great?

ive been thinking about this for a while. and i just know that ill get a few negative responses. but i really dont care. its been bugging me for a while. ive often heard people say what is god? so people preach about god and how good he is. yet they hate murders. god takes babies away from their parents,he takes people away from their friends. he takes parents away from their loved ones. and god is still good? people say god took others away as he had better things planned for them. if he hadnt taken them away,maybe they would have planned better things for themselves. god has murdered more people and animals than anyone in the world. so please dont preach that god is good,god is great. cause he isnt. to me,god is a murderer.
