Should a monotheistic God ever be considered good or great?

* One more important asterisk* -

Note - While I have mentioned that this thread is based on generally accepted attributes of monotheistic God, I will not base my discussion on specific actions of any particular God as mentioned in His/Her holybook. The storybooks and holybooks of any religion may have a God doing things contradictory to His/her attributes. For example a self proclaimed perfect God regretting His past action. I will not take it as claim that a monotheist God can commit mistakes. It is simply a case that religious writers messed up their holy books. Have seen countless cases of such goof up by writers of Hinduism and if I may believe western atheists then even Abrahamic religions have certain contradictions much like Hinduism. I am for discussing it in accordance with taking general attributes of monotheistic god as our premise.
