If Hitler converted to Islam before his death, would his sins have been forgiven?

Re: If Hitler converted to Islam before his death, would his sins have been forgiven?

Sir,
here is another hypothetical Scenario...
Imagine that there is donkey ...he grazes day n night...and does adultery..as u know animals dont marry each other. There is no wedding and no Valeema...
Further Imagine that this donkey undergoes genetic mutation and converts into a human being. Furthermore...this human turned donkey starts studying religion and fortunate enough he decides to become a muslim.
Now Mecernary do u think that this mutant human will be forgiven or will he be laid adultery charges in the life hereafter?
I dont want to offend anybody...but its just a hypothetical case for some ethical brain storming.
