The skit "Life Again" is about how sin affects you and your relationship with Christ. Once you've said "yes" to sin, its that much easier for you to keep saying "yes". You keep 'opening' the door to sin. The only way to close the door is by asking for help in the sacrament of confession.
The Main Character (MC) does not run to Jesus, for if she does/did, He would be there in less than a heartbeat. When it appears as if she is, she is actually sinning again; going back to what is familiar. These are her 'regular' sins.
The teens who play the various sins (anger, jealousy, pride, etc.) are sins, they are not people. And, therefore, the focus is not on the sins but on the MC and her relationship with Christ.
When a sin comes into the MC's life, the sin always pulls her away from Christ.
The action of the sin ~ through the MC's choice ~ results in Christ being beaten as well. Every sin we commit affects our relationship with Him. That is why the MC's beating is mirrored upon Christ. However, Christ maintains His mercy and His love no matter what we do to Him and to ourselves. He is always waiting for us to ask for His help.
The more sins you commit, the more there is a gap in your relationship. The only way to repair that relationship is to seek His mercy in the sacrament of Reconciliation.
Christ is with us through everything! Yes, everything.
