God glorifies Himself in two ways. In His grace in saving the elect and in His justice in damning the reprobate.
(So he creates people he KNOWS will fail, just so he can punish them. How is that loving?)
You know, it seems that everyone expects God to be some soft fluffy bunny type deity who just turns a blind eye and refuses to punish people people because he love, all love and nothing but love. You seem to want to require Him to be God almatey rather than God almighty. God is holy, just and righteous. Sin is abhorant to Him and we have broken every one of His laws. God is merciful and graceous if you are still alive and well this time tomorrow. Grace is undeserved. It can't be demanded.
