Ya, I'm sure they were angels who had the Jews' best interests in mind
look I like you man but with a comment like this it shows me that you really don't know what you are talking about.
But I do know because I have read more books than I can count about the subject with primary focus on the Reichs SS and Waffen SS and especially everything about Concentration camps etc. etc.
So let me tell you and seriously I am not talking down on you but you are misguided.
For starters, there is a huge difference between the Waffen SS (the fighting arm of the SS) and the Einsatzgruppen who were mostly drafted from SS police battalions.
To be accepted you had to be up to the standard of racial doctrine of the third Reich but there are many accounts of complaint letters send by officers of the Waffen SS in regards to orders given to them by the High Command how to treat Russian POW after Barbarossa was in full swing, that is just one example that not everybody who was in the Waffen SS did also participate in the mass shootings of jews in the east.
In fact (and If you want to I can recommend some good books on that subject unfortunately all written in German) the mostly volunteers who were shooting and volunteered for the Einsattruppen were a very small % of the overall SS.
The Waffen SS was an elite military Unit, no different to the US Marines - they were the firebrigade of the east to be used to halt the enemy what ever the cost, no other unit has received that many casualties than the SS has.
Now, once again an entirely different matter was the drafting of SS from foreign countries - most of these people had no love for Hitler at all or no ill feelings towards jews, but they were simply rounded up and given a uniform - take my grand dad for example he didn't know he was going to be in the Waffen SS until he got his uniform.
There are so many more excamples why the Waffen SS was not what a lot of people want to believe - the National geographic educated person thinks of any Waffen SS member as a member of the death scull brigade, but did you know that there was an uproar amongst the Waffen SS when members (mostly old) SS who were ordered to become Concentration camp guards were ordered to wear the death skull sign, until than it was only the elite of the elite that were allowed to wear that and there was a general feeling of disgust that "these" SS members who were mostly the once that the HQ wanted to get rid off where wearing now a sign that was highly regarded and by many worn with pride.
If you can read German I highly recommend a book called Saat in den Sturm - its written in a very honest way by the youngest SS German volunteer who took part in the french invasion and later in the eastern front - its a very honest book and the author himself since than has died i believe.
