The archbishop of the mainly Christian country weighed into the discussion on Wednesday following a spate of protests in Kinshasa over legislation that that would enable Kabila, who has been in power for 14 years, to extend his term beyond 2016 when his second mandate ends.
"Certain political figures, along with law enforcement agencies, are sowing despair and creating insecurity," Archbishop Laurent Monswengo said in a statement.
We denounce these actions which have caused death and we are launching this plea: stop killing your people.

Speaking from Belgium on Tuesday, DR Congo opposition leader Etienne Tshisekedi called on the Congolese people to force a "dying regime" from power.
Tshisekedi, 82, who is in Europe recovering from illness, has been in opposition since the 1960s, previously taking on the leader Mobutu Sese Seko as well as Kabila's father Laurent Kabila.
Kabila, now 43, is the son of former president Laurent Kabila who as a rebel leader in 1997 toppled Mobutu.
