Umm, I have this repop code, but i cant get it to work.. When i kill something, it dissapears, but wont respawn O.o

This is the code:

mob
proc
MonsterAttack(mob/M)
if(src.attacking == 0)
src.attacking = 1
//var/parrylist = list("High","Middle","Low")
//continu = 1
//else
// continu = 1
//tryagin
//if(continu == 1)

view() << "[M] takes [src.Str] damage from [src]!"
M.Hp -= src.Str
Death(M)
sleep(src.Delay)
src.attacking = 0

mob
proc
Death(mob/M)
if(src.type == /mob/player)
Playerdie()
else
if(src.Hp<=0)
view()<<"[src] has been killed by [usr]!"
del(src)
therepop()
Playerdie(mob/M)
if(src.Hp<=0)
view() << "[usr] Died!"
src.loc = locate(1,1,1)
src.Hp = Max_Hp
therepop()
proc
therepop()
world.Repop()
sleep(150)


mob
proc
NonAggresiveLook() //name of proc
var/mob/player/M //variable M has to be mob/usr
while(src) //while src is stil kickin
if(M in oview(5)) //if M is in oview(5)
if(M.name in src.killlist) //now if M.name is in src.killlist, this has it only attack if attacked!
walk_to(src,M,1,4) //src walks to M until 1 block away, moving 4/10ths of a second
if(M in oview(1)) //if M is in oview(1)
step_towards(src,M) //src steps toward M
else //if usr.name isnt in src.killlist
//src.killlist += M.name
sleep(15)//pauses for 1 and 1/2 seconds
step_rand(src) //step randomly on the field
break //breaks out of the while loop
else //if M isnt in oview(5)
for(M in view(src)) //for all Ms in view(src)
break //breaks out of the while loop
sleep(5) //pauses 1/2 second before redoing loop
spawn(2) // pauses 2/10 of second before redoing proc
