Suicides are caused primarily by mental illness, and can be committed through many means other than firearms. Trying to stop suicides by removing firearms is a pointless endeavor, similar to trying to cure a cold by keeping the patient from coughing. Homicides are similar in that one can commit homicide by many means other than firearms, though firearms allow doing so from a much greater distance; however, again, the root cause is mental illness, and attacking firearms is a waste of effort compared to trying to fix the root cause. As for accidental deaths, they have nothing to do with suicides and homicides, and the solution there is to teach people how to not point the firearm at something they don't want to kill (among other safety rules, like not keeping the weapon loaded unless absolutely necessary).
