To pull out and only have Crimea would be an absolute embarrassment for the Russians and Putin would know that would be the end of him.
Dictators don't typically have a quiet retirement, things dont usually turn out well for them, so Putin will know what's at stake.
He is likely to double down now and things could get markedly worse. I can forsee tactical nukes soon as he is cornered and despite what the Russians tell their people, this has been a complete embarrassment for them already.
