How to convert or add a set(Ids) into a list<Sobject> in apex?

Set<Id> parSet = new Set<Id>();
List<Account> DelAccLst= [select id from account where id in : parSet];
Database.DeleteResult[] drList = Database.delete(DelAccLst, false);
// Iterate through each returned result
for(Database.DeleteResult dr : drList) {
    if (dr.isSuccess()) {
        // Operation was successful, so get the ID of the record that was processed
        System.debug('Successfully deleted account with ID: ' + dr.getId());
    }
    else {
        // Operation failed, so get all errors                
        for(Database.Error err : dr.getErrors()) {
            System.debug('The following error has occurred.');                    
            System.debug(err.getStatusCode() + ': ' + err.getMessage());
            System.debug('Account fields that affected this error: ' + err.getFields());
        }
    }
}
