Q. Re- question 1561 where we wrote; “The Torah rules (Bereshis 9:5 ), “the blood of your own lives I will demand of you.” (Baba Kama 91b) and looses his part in Olam Habaah, therefore Shulchan Aruch (Y. D. 345: 1) rules that one who commits suicide in principle is denied the after-death honors and privileges of aveilus (mourning): No keria or rending of clothes and eulogies are offered for the deceased, and burial in the main section of the Jewish cemetery is normally not allowed.”
If the deceased is an uncontrite murderer, is there any difference in conduct towards the deceased? Or is a suicide worse than a murderer of others, and why?

A. The “uncontrite” murderer, we assume means incorrigible or one who did not do teshuva. In principle, as we mentioned; “Halacha considers suicide to be tantamount to murder.” In practice however, a murderer can repeat his sin many times as opposed to a suicide. More so, most often suicides are committed by individuals in a mentally unfit state. As we wrote; There are also many specific Halachos that define who in fact committed suicide and who did not, therefore, a competent Rabbi should be consulted.
Horav Shlomo Miller’s opinion is similar. However, the Rov added that from a different angle, a suicide can be seen as more severe, since we would consider someone murdering a close relative such as his father as more evil and heinous than killing a stranger.
