EDITed to add: but I have a hard time believing that the ECB will tolerate deflation.
The ECB is much more comfortable with deflation than inflation.
Here's my reasoning: Germany is the largest economy and has the strongest export sectors which results in having more money to put into the till. As a result, the ECB is indirectly run by the Germans, whether the rest of Europe likes it or not.
Germans are very risk averse and have a long memory about hyperinflation that led to terrible things happening across Europe, the least of which was the complete and total destruction of their own personal wealth. Unemployment will be tolerated, but not inflation. German politicians will be re-elected in a high unemployment environment, but not a high inflation environment.
In a nation of savers, deflation rewards savers and penalizes borrowers. And, Germany is a nation of savers. So politically deflation would be much more acceptable than inflation, even though deflation is currently unlikely to occur.
Keep in mind also that Germany runs a government surplus (!) and has for the past couple of years (!!!). So, technically, they don't need to borrow new money, even though I'm sure they do to keep the gears moving.
