Prayaschitham is a way of convincing and reinforcing oneself not to repeat the mistake and owning up the mistake and ready to help lessen the pain of the victim to the possible extent.
Once a 'sin' is committed and the person realises his wrongdoing, then he/she can confess and hope that God would forgive him and his burden becomes less. There is no point in carrying 'Guilt' for a long time. There are numerous crimes wherein after a long time the criminal comes forward to confess because "guilt eats his soul every moment' and makes him confess.
We cannot keep committing the crime again and again or do something fully knowing about its implications and then run off to confess. Confessing and hoping to get pardoned must not be taken lightly, among Christians it's well-known practice. I'm not sure among Hindus, is there a practice wherein you can confess to the priest at a temple. People believe that a holy dip in a holy river ( Ganges) gets rid of all their sins.

Confessing doesn't wash away your sins, it merely brings them to light. Rest is upto you.
Confessing your sins will restrain you from escaping. Now that you're cornered, act; act wisely and sinless.

'Don't miss the Donut by looking through the hole'- Anonymous.
Always talk to your inner self couple of times when you are in doubt of doing a particular task. Go ahead with it only if your inner soul asks you to proceed, then I feel you will never have to repent in your life.
"Do not give up, things might not favour you always"
Who isn't a sinner? I think all of us have sinned, and by sin, I mean things that we do – not just in action, but also in thought and in words. If an evil thought crosses my mind, it is a sin. If I think of your failure, I am committing a sin, because I get pleasure out of my thoughts.
Coming to confessions, we can confess to God, directly. But, when we confess to a priest, we acknowledge our faults and it is humbling. We open ourselves and share our darkest secrets, something that we would be ashamed of. It makes us realise our faults and we seek forgiveness for those trespasses.
One of our prayers asks for forgiveness thus – "…I have sinned through my own fault, in my thoughts and in my words, in what I have done, and in what I have failed to do…" We seek for pardon our sins - our sins of omission and sins of commission.
