I know what its like to lose faith, I've been working very hard on regaining my own. I don't know what to say. I don't think anyone will ever be able to give you the answers you need. Its my belief that God is in the individual and so in order to get answers, you have to look into yourself to better understand. As for how he can allow injustice to continue as it is, I don't think thats something we'll ever understand. I just look at how I am and know that I wouldn't want to turn out any other way. I have God to thank for putting me through all the bad things I've been through and I accept him as not purely benevolent but two entities of creation and destruction, for in my eyes destruction is creation and wicked things happen to the good to make them stronger. I guess what I'm really trying to say is, we could tell you that there is or isn't a deity, we could try to explain him to you but the answers are all in you and the only way you're ever going to find them (in my opinion) is by looking into yourself. I wish you luck.
