A priest has warned that further bloodshed will ensue if revenge is sought among the biker community for the murder of one of their "brothers".
At Andrew O'Donoghue's funeral mass, Fr Tom Ryan - a close friend of the victim - called for "peace and forgiveness".
Fr Ryan, retired parish priest of Murroe, said: "The sad thing about life today is that we have become accustomed to this kind of bad news, and it doesn't seem to bother us much any more until it comes to our own doorstep."
Mr O'Donoghue (51) was shot outside the Road Tramps Motorcycle Club on Saturday after a dispute spiralled out of control.
Fr Ryan condemned the brutal slaying, and said a rise in gun murders had left parts of Irish society with "a complete lack of respect for life".
"Unfortunately it is almost an everyday occurrence now. This is not the Ireland in which I grew up."
Fr Ryan said he was trying to understand "this craziness in our world, and in our own country; trying to understand lives ending needlessly; and trying to understand a complete lack of respect for life".
In a stark warning, Fr Ryan said: "Move away from the old regime of an eye for an eye, or a tooth for a tooth"
Mr O'Donoghue's brother, Peter, described him as "a legend". "Andrew loved his partner Kate. He adored his daughter Ava. His home was Murroe and the Road Tramps was his life." Loud applause erupted after he added: "The truth is very powerful and will always prevail."
Four men have been questioned by gardaí about the killing.
