Was George justified in killing Lennie

I think that George had no choice on killing Lennie because Lennie would get him in trouble. George did not want any of these problems with Lennie. Lennie is the cause of all of George's trouble. Lennie was slow ,he would say something and it wont make sense.

Is history worth studying?

I believe the history of the holocaust is a serious subject to look through the fact it can happen again. A lot of peoples lives were in peril . Who would wonder what will happen next. Past history can teach us how difficult it was then, compared to now.  

I wonder how it would be if Lennie and George both was disable. What would there life be .I think they would be dead by now
