The goodness of God

In the S.D.
Greetings to the esteemed Rabbi,
I wanted to ask whether there is evidence that God is good?
After all, if we assume that God is the best, then He does not even have the ability to do evil. Even temporary, momentary, and small evil.

In the world around us we see bad things happening, for example, earthquakes that kill and injure thousands. So how can we claim that God is good?

This question consists of two parts –
1. How do we know that God is good? (I assume that from any empirical finding we can assume that God is bad but only does a little good, as opposed to the other way around)
2. If it is good, then how does it align with reality? (And vice versa if it is bad…)

With thanks,
Kobe.
