dcmd_kill(playerid,params[])
{
    if(GetPlayerWantedLevel(playerid) >= 1) return SendClientMessage(playerid, -1, "You are wanted, you cannot kill yourself!");
    SetPlayerHealth(playerid, 0);
    SendClientMessage(playerid, -1, "You killed yourself!");
    return 1;
}

Here. This prevents people with a wanted level to /kill.

Out of three of these posts, this is the most efficient way to do this. It has less lines and looks better.

EDIT: Below post, not really. Mine looks more easier to understand, in my opinion..
