"don't worry about teshuva yet"
This is something I see alot here, if not explicitly, strongly implied.
if I'm understanding correctly, the reason for this approach is that mixing in teshuva can make people feel alot worse when they fall, and more hopeless. Especially when lives are at stake, it's important to get things under control for their own sake, and not get overly myopic.
And i get it.
I think however, that this comes from a misunderstanding of teshuva. Teshuva process has four steps azivas hacheit, charata, viduy, and Kabbalah Al ha'asid.
As far as I know everyone agrees that, azivas hacheit, or not repeating the sin, comes before Kabbalah Al ha'asid, or accepting to not repeat the sin.
For some things, azivas hacheit is simple. Someone usually doesn't eat shaleshuedes on shabbos, so he decides to start. Someone forgets tefillin or tzitzis, once in a while, and he decides to be more consistent. He is ready for Kabbalah al ha'asid.
For things in life that are harder, that we most desperately need to fix, azivas hacheit is really, really hard. Someone who loses his temper easily, or struggles with relationship with parents/kibbud av va'em, or anything that requires changing ourseves and not just an action, is a long road that requires planning and small steps and truckloads of time and effort. Big picture. Practical steps. Goals along the way. Azivas hacheit for the real stuff can take months! Years!
And gye might be the first I've actually engaged in teshuva. Yes, from year to year ive tried small Kabbalos. I've said viduy and promised to fix the worst parts of me. But that was not real teshuva. Yes, there was charata, yes, there was viduy, and yes there was a kabbalah Al ha'asid. And I really meant it.
But there was no azivas hacheit. For some reason, I avoided it, and I think it's the easiest step to "forget". Because I can feel like i've done teshuva without it, and it's hard! Really hard!
But it's the core of teshuva.
So yes, it's dangerous to focus on viduy, charata, and Kabbalah Al ha'asid alone. I know from experience. It left me burnt out and hopeless and alot less motivated/likely to change than if I just left those alone. But thats not teshuva. It's a stupid recipe for disaster.
Let us all proudly partake in azivas hacheit, knowing that it takes time effort, planning and a whole lotta guts. Azivas hacheit is a process. And when we realize this we can proudly be knee deep in the teshuva process, in a place where we realize that setbacks and failures are part of the journey.
