it is most definately self-destructive......you immediately become somthing new, someone else.....your "essence" will change when that child is born......just the very idea that name changes from "brother and/or son" to "dad" signifies your essence changin'....and within that sense, the self before this change is destroyed.....but itz not necessarily a negative destruction....it is positive; there is a lot more to learn if you have a child (i don't have one, but it would seem apparent life changes when a new life is introduced into your life.....even something as simple as findin' a new love changes your life in some fashion....imagine how it is when you have a child)

at the same time it can be negative, but it does depend on many factors.....the most crucial of which is probably age.......a 30 yr old new parent won't feel the negative effects of their new born child the same as a 19 yr old.....relatively speakin'
