Just because someone picks up a good word and incorporates it into their title doesn't mean anything. Are the LDS the real saints because they incorporate the word "saint" into the name they chose for their supposed church. No. Neither is the Catholic Church the true Church because they chose the name "Catholic" as their title.
And yes, they murdered countless people who did not agree with them. They were in power. The Jewish religious system that was in power at the time of Christ rejected and murdered Him. Being the religious system in power does not make you right. The Jewish religious system was abolished and will not come back until Jesus comes again.
In fact catholic means that all people who believe in Jesus are a part of the universal Church, not that you have to be "Catholic" to be a member of the universal Church.

Then Our Lord would have NOT founded ONE Church, appointed Apostles to govern that ONE Church and given them the power to do so.
“Jesus said to them again, ‘Peace be with you. As the Father has sent me, even so I send you.’ And when he had said this, he breathed on them, and said to them, ‘Receive the Holy Spirit. If you forgive the sins of any, they are forgiven; if you retain the sins of any, they are retained.’ “
