You are trying to convince yourself by repeating this.
Ronaldo since changing clubs has achieved more success than Madrid, there are no prizes handed out for losing in CL. Also, it's ludicrous you are pinning Juventus CL failures on him. He literally scored every single one of their CL goals in knockout rounds for 2 years straight. Juventus managed 7 goals combined in 6 matches across his first two season. He didn't score this year but managed to assist 2. So, his overall contribution is 7 goals and 2 assists in 8 KO matches for Juventus where they have scored 12 goals combined, that's 75% contribution. Also, it's disingenuous to bring up Juventus reached 2 CL Finals in 3 years before signing Ronaldo. They were an ageing side, in need of replacement pretty much across the park. Their signings have been poor, and not to mention, Pirlo was a terrible appointment this season.
Given your posting history, I should've expected more biased takes out of you. But, this is something else. Now, I'm sure you'll move goalposts again and spring another mental gymnastics. That's what you've been doing for 7 years now, which is quite pathetic.
