Yeah, it could even be argued that they do help others in need during natural disasters by rebuilding JW's homes,
I'm not even sure the extent to which they do that, I was always under the impression it was lip service and photo opportunities only.
The same arrogance that tells JWs they are correct in their beliefs also has a tendency to enable them to isolate themselves emotionally and show little empathy, even to fellow witnesses.
This isn't true for all witnesses - I'm sure there are caring elders and congregations but by and large my feeling is that's the exception, not the rule.
