No, it will likely be canceled, either automatically or on the spot at the border :
The Finnish Migration service on both FAQ and RP Cancellation pages has that to say :
If you move permanently away from Finland, your residence permit will be cancelled.
Your fixed-period or temporary residence permit will be cancelled if
- you move from Finland permanently
- you otherwise reside outside Finland for a permanent purpose for two years uninterrupted.
An EU Blue Card will be cancelled if you have been unemployed for three months without interruption. You must always return the card when the permit is cancelled and the card is voided.
The important part is :
As you will likely not stay employed as a Blue Card holder, it will automatically cancel after 3 months of you leaving your job.
If you stay employed to your Finnish employer, while moving abroad, this might be different and then you would have your permit canceled after 2 years of permanent residence outside of Finland
I couldn't find a definition of residence from the Finnish authorities of what exactly is residence for such purposes, but the citizenship definition is :
Your continuous period of residence is interrupted if you leave Finland regularly for such long periods of time that you can be considered to reside the most of your time outside Finland.
The following period of absence from Finland will not interrupt your continuous period of residence but it will not be calculated as continuous residence time:
- a period of absence that lasts longer than six months but one year at maximum
This means that practically speaking, any absence longer than 6 months (usually more than 183 days), will count you as not-resident for the year and doing that for 2 years, you will have your permit cancelled.
Depending on circumstances, you might be able to apply to the migration service to prevent those cancellations :
If you do not want your residence permit to be cancelled because you are living abroad, you should apply within two years of moving abroad to have the cancellation prevented. Apply by filling in the form OLE_PER in Finnish, Swedish or English.
But, it will imply that you will come back at some times which will not be the case if you move permanently
TL;DR Have your RP cancelled formally (procedure) and applying for a Schengen visa (if applicable) when you want to visit back is likely the preferred way in your situation.
If you decide not to, never use it again to enter the EU or you will be in a huge lot of trouble at the border (quite unlikely but still a possibility, when the EES will be rolled out you can be confident that you will have such issues) because the unemployment clause (after 3 months, if that applies, the other clauses if it doesn't apply) will likely have been triggered either automatically or directly at the border.
EDIT: It might also be nasty not to formally cancel your Blue Card :
You must always return the card when the permit is cancelled and the card is voided.
Identity documents are always property of the issuing government, so, assuming you don't return your Blue Card, you may end up in trouble as it is required to do so (usually, that would be a fine, but I don't know for Finland exactly)
All emphasis are mine
