Please Help - When used command "systemctl stop abrtd", I sought message "active: failed" on "systemctl status abrtd"

*Issue
I don't want to use abrtd , because abrtd's logs used /var's size
so, I was as bellow

1. systemctl stop abrtd
2. systemctl status abrtd

But,when I used "systemctl status abrtd", I sought message "active: failed"

[root@localhost ~]# systemctl status abrtd

*My opinion
While abrtd was creating a "ccpp- * file" in "/var/spool/abrt/", abrtd was stopped(systemctl stop abrtd)
and a crash occurred.
Therefore, failed.

*Request
1. What caused the problem?
2. Currently Active: Failed. How can I make "Active: inactive (dead)"?
