2. What could happen if the node application is down before I able to kill it?

Answer 1

1.Do I need to kill sometime this process?

Ans: If that process is not going to get used further then you better kill it once its job is done.

2.What could happen if the node application is down before I able to kill it?

Ans: If your main node application goes down then your child processes are ultimately gonna get killed so you don't need to worry about it.
