What is the purpose of the prayer in Fire Force?


I'm not too far in the series but I can't see any use in the prayer yet.  
First I thought the prayer either weakened the infernal or boosted the
firefighter.  
Then I thought the soul needed the prayer to be "freed".

For example, on D.Gray-Man:

> A soul can either be freed when killed by exorcist innocence or destroyed
> when killed using a different method.

Does it make a difference if they pray or not in Fire Force?




Great pressure is pressed on people if they feel they are killing people (or
at least I think so). The Fire Force was set up to save people instead of
killing, although they may be literally killing all the time.

In order to maintain a sense of justice and mercy, prayers are needed, not
only to confort the family and relatives of the dead, but to ease the feeling
of guilt of the firefighters.
