Comparing what Morrison has done with Damian and what Slott has done with Peter are two entirely different things. Peter Parker is still alive albeit not physically , and as I've mentioned in the Marvel thread many times now, Superior Spider-Man is part of a larger still ongoing story line that has been unfolding since Slott took over Amazing full time. Morrison is concluding his run and concluding a character arc that he created and started himself. I don't think the two are comparable at all, nor does Slott need to "take lessons". Besides which everyone knows that Peter will be back in his body at some point...we don't know that with Damian right now.
