Same reason as above.
```golang
return nil

Review Comment:
There are two questions here
1. Events are not always up-to-date. We always retrieve the latest object,
which may have been deleted. This logic can lead to infinite retries.
2. Redundant logic, same as line 138.
```go
if !k8serrors.IsNotFound(err) || (k8serrors.IsNotFound(err) && ev.Type !=
types.EventDelete) { return }
if ev.Type != types.EventDelete { return } # Redundant
<==>
if !k8serrors.IsNotFound(err) { return }
if ev.Type != types.EventDelete { return }
```
